Psychological Properties of Colors

Color psychology is the study of color as a determinant of human behavior. However, the interface between color and environmental stimuli is a highly complex interface and one which is open to the influence of a large number of factors. There are several reasons why colors are able to influence how we feel. "We react on multiple levels of association with colors -- there are social or culture levels as well as personal relationships with particular colors," explains Leslie Harrington, executive director of The Color Association of The United States, which forecasts color trends. "You also have an innate reaction to color. For example, when you look at red, it does increase your heart rate. It is a stimulating color. This goes back to caveman days of fire and danger and alarm."

There are four psychological primary colors - red, blue, yellow and green. They relate respectively to the body, the mind, the emotions and the essential balance between these three.

Investigate comprehensively on how colors affect different people, either individually or as a group, is something some people build their careers on. And there’s a lot to it. Something as simple as changing the exact hue or saturation of a color can evoke a completely different feeling. Cultural differences mean that something that’s happy and uplifting in one country can be depressing in another. 
For example, in China, red is the color of prosperity and happiness. It can also be used to attract good luck. In other eastern cultures, red is worn by brides on their wedding days. In South Africa, however, red is the color of mourning. Red is also associated with communism. Red has become the color associated with AIDS awareness in Africa due to the popularity of the [RED] campaign.


The Psychological Effects of Color
While perceptions of color are somewhat subjective, there are some color effects that have universal meaning. Colors in the red area of the color spectrum are known as warm colors and include red, orange and yellow. These warm colors evoke emotions ranging from feelings of warmth and comfort to feelings of anger and hostility.
Colors on the blue side of the spectrum are known as cool colors and include blue, purple and green. These colors are often described as calm, but can also call to mind feelings of sadness or indifference.


Color Psychology as Therapy
Several ancient cultures, including the Egyptians and Chinese, practiced chromotherapy, or the use of colors to heal. Chromotherapy is sometimes referred to as light therapy or colourology and is still used today as a holistic or alternative treatment.
In this treatment:
Red was used to stimulate the body and mind and to increase circulation.
Yellow was thought to stimulate the nerves and purify the body.
Orange was used to heal the lungs and to increase energy levels.
Blue was believed to soothe illnesses and treat pain.
Indigo shades were thought to alleviate skin problems.

Experts have found that while color can have an influence on how we feel and act, these effects are subject to personal, cultural, and situational factors. More scientific research is needed to gain a better understanding of color psychology.


Four Psychological Primary Colours
In colour psychology, red, yellow, blue, and green are considered as the primary colours. These colours represent body, emotion, mind, and the essential interdependence and harmony between these three elements, respectively.

Red, with its extended wavelength, is considered a strong colour, hence its association with physical aptitude. Although it is not the most vibrant of colours, red has the capacity to seem closer to a particular observer than it actually is, therefore scoring high when it comes to attention attraction.
Red has the capacity to trigger physical responses from human beings and this is the reason why it has been employed to serve utilitarian purposes like the traffic light signal for stop. This colour is also deemed masculine and is said to awaken a person’s fight or flight instinct. Some of red’s positive attributes include augmented sense of enthusiasm, warmth, and energy. The less favourable attributes are stress, hostility, and insubordination.

I have personally thought about why colour red could associate with physical aptitude, as back in the old time when there was no discover of electricity, people used to set up fire for light at night, it brightens the darkness and informs the other tribe of people that there is others and be alert! Fire keeps humans warm which attributes the sense of enthusiasm, warmth and energy. 

Human emotion is directly associated with the colour yellow. Colour psychology characterizes yellow as a potent emotional stimulator, with its considerably long wavelength.
Positive thinking and confidence are just some of the human attributes inspired by this colour, but, people who play around this chrome have to ensure utmost discernment since its improper usage, relative to the other shades from the colour wheel, can yield undesirable effects.
Some of the negativities that misuse of the colour yellow can induce include; apprehension, terror, intense sadness, irrational thinking, and emotional vulnerability.
Once properly managed, though, yellow can just as easily speak of unrivalled self-esteem, congeniality, optimism, and even artistry.

When we look at twilight when and where the sun sets, the beauty or somehow the colour of sunset (yellow) brings us lots of emotions that could be the memories that's happened before, or the feelings of beautiful nature appreciation. 

Human intellect, from the perspective of colour psychology, manifests all known shades of blue. This calming colour has the capacity to rouse us intellectually. Potent shades of blue inspire clarity of thought, whereas the softer variants allow utmost mental focus and serenity of the mind.
Blue has been generally perceived as an endearing colour. In various cultures from all over the world, this chrome has gained a rather positive interpretation. It goes without saying, though, that blue also has its own negative associations such as coldness, isolation, and emotional unavailability.

When it's sunny during the day time, the sky will be blue, sunny weather leads human moods to a positive state. Blue sky is also a pure sky that has its clarity.

Green is, arguably the most germane of all the primary colours in colour psychology. It facilitates the harmony between the other chromes: red, yellow, and blue. Visually, green is able to emanate a striking appearance without being overly imposing, hence observers can enjoy it in all possible shades or tones.
On a primordial level, humankind is endeared to green due primarily to its abundance in nature. It speaks of not only prosperity, but also harmony. However, it is imperative to keep in mind that misuse of this colour can inspire a sense of atrophy related to boredom and stagnation.

Color as Emotion
A knowledge of color theory helps us to express our feelings in an artwork. The language of color has even entered our vocabulary to help us describe our emotions. You can be ‘red’ with rage or ‘green’ with envy. We often speak of bright cheerful colors as well as sad or dull ones. A ‘grey’ day may be depressing and result in a feeling of the ‘blues’.
VINCENT VAN GOGH (1853-1890) 'Sunflowers', 1888 (oil on canvas)
Hope and Joy: The paintings of Vincent Van Gogh show an instinctive understanding of the emotive properties of color. In this version of 'Sunflowers' from the National Gallery in London, he uses warm yellows to create an energetic image that radiates feelings of hope and joy. On the gallery wall this painting is surrounded by a thick dark brown frame and glows like a backlit image from within.

PABLO PICASSO (1881-1873) 'The Tragedy', 1903 (oil on canvas)
Sadness and Despair: Another effective use of emotive color is found in the paintings of Pablo Picasso. Between 1901 and 1904, Picasso painted in monochrome tones of blue which reflected his low psychological state. This was triggered by the death of his friend, the Spanish painter Carlos Casagemas, who shot himself because of his unrequited love for the artists' model Germaine Pichot. This chapter of his work became known as his 'blue period'. In 'The Tragedy' (1903) he uses cool blues to evoke the chill of sadness and despair in a typically gloomy subject from this period.
According to English dictionary, blue has a few of definitions, one of them states: informal
(of a person or mood) melancholy, sad, or depressed. "he's feeling blue"

ANDRÉ DERAIN (1880-1954) 'The Pool of London', 1906 (oil on canvas)
Noise and Activity: AndrĂ© Derain uses the clash between contrasting warm and cool colors to express the noise and activity of this busy dockyard. He creates the illusion of depth in the painting by using warmer colors in the foreground which gradually become cooler towards the background. This organized arrangement of colors in a landscape is called Aerial Perspective.



Rainbow Color
Rainbows form a significant part of human culture. They occur frequently in mythology, and have been used in the arts. One of the earliest literary occurrences of a rainbow is in Genesis 9, as part of the flood story of Noah, where it is a sign of God's covenant to never destroy all life on earth with a global flood again. Rainbow flags have been used as a symbol of hope or social change for centuries, featuring as a symbol of the Cooperative movement in the German Peasants' War in the 16th century, as a symbol of peace in Italy, and as a symbol of gay pride and LGBT social movements since the 1970s. In 1994, Archbishop Desmond Tutu and President Nelson Mandela described newly democratic post-apartheid South Africa as the rainbow nation.
In Greco-Roman mythology, the rainbow was considered to be a path made by a messenger (Iris) between Earth and Heaven. Rainbows are generally described as very colourful and peaceful. The rainbow occurs often in paintings. 
Peter Coffin's Untitled (Rainbow), 2005


Ugo Rondinone's Hell, Yes!, 2001

In contemporary visual art, the rainbow often appears as well, notably in Peter Coffin's Untitled (Rainbow), 2005, and in Ugo Rondinone's Hell, Yes!, 2001. Like many other cultural references to the rainbow, these either emphasize the possible sublimity of the natural world or the cheerfulness, joy, and celebration often culturally associated with a profusion of colors.


Our main source of light on this planet is the sun.
We are naturally driven by the energy of sunlight - it provides warmth, growth for food, ability to cook that food, and much more - the sun's energy is vital to our quality of life on a daily basis.
The sun drives our world and dictates much of our behavior. The rising sun stimulates activity and a state of alertness, while the blue light of evening brings on relaxation, and finally full darkness indicates a natural time to sleep for most people.
One of the benefits we receive from the sun's rays is the energy produced when light waves become color!
Emotionally we respond to colors as they fit the time of day or year. The reduction of sunlight on a cloudy day or the long months of winter can significantly affect our emotions. Lack of sunlight can cause mood swings, depression, low energy level. Most of us notice a fresh, cheerful, vibrant feeling when Spring arrives after a long dark winter.

The seven color rays are spiritual forces emanating from the white light. They are perpetually vibrating - not only on the surface of the earth - but also above and through it, encircling the globe in streams of endless energy.

Stages of Death
My cat who was also my best friend and family had passed away a few days ago, I didn't accept his death well in the beginning, my feelings and thoughts were a mess, I didn't know what I was thinking and feeling. Maybe I was thinking and feeling so many things at one time so it makes everything a mess. I felt lost, I couldn't burry him and my pain, I kept weeping. Knowing the truth that he doesn't exist in our world anymore gives me lots of memories of him, I memorise pretty much everything and every moment that I had spent with him; and this memorising process makes me feel more and more sad. 
Later on the day I lost him, I had watched this video on Youtube, it's about the 5 stages when facing to death and loss. You can watch it below:
Stage 1: Denial, when my best friend wasn't able to breath well and even stand up, I deeply knew that he couldn't make it on that day anymore, but I denied what I deeply knew, instead I kept telling my best to hold up and not to leave us alone, a part of me at that moment still believed that he could still survive from the pain he was suffering and death would not take him away from me. 
Stage 2: Anger, I hated the vets who couldn't save my best friend, even though the vet tried their best, I still blamed for what they couldn't have achieved and I had an enormous  hatred of their low ability. 
Stage 3: Bargaining, I prayed and begged god (even though I am not a very religious person) not to take my best friend away, I kept hoping that my best friend will recover and heal and come back to that healthy cat and I kept hoping that he will survive from his sickness.
Stage 4: Depression, after my best friend's funeral, I got home and snapped, started roaring with weep and tears. I could not accept that one of my family was gone and no longer living with us. 
Stage 5: Acceptance, it's been 3 days since my friend had left, I started crying less and less, accepting the truth that he had gone to paradise living in peace, even though there's something missing and makes me feel empty. But what happened had already happened, I just have to learn to accept, move on and remember to smile.





Emotion of Sadness
Sadness is emotional pain associated with, or characterized by feelings of disadvantage, loss, despair, helplessness and sorrow. An individual experiencing sadness may become quiet or lethargic, and withdraw themselves from others. Crying is often an indication of sadness.
Sadness is one of the "six basic emotions" described by Paul Ekman, along with happiness, anger, surprise, fear and disgust. Sadness* is a common experience in childhood. Acknowledging such emotions can make it easier for families to address more serious emotional problems, although some families may have a (conscious or unconscious) rule that sadness is "not allowed”. Robin Skynner has suggested that this may cause problems, because with sadness "screened-off" we are left a bit shallow and manic.While being one of the moods people most want to shake, sadness can sometimes be perpetuated by the very coping strategies chosen, such as ruminating, "drowning one's sorrows", or permanently isolating oneself. As alternative ways of coping with sadness to the above, cognitive behavioral therapy suggests instead either challenging one's negative thoughts, or scheduling some positive event as a distraction.

Poster "The Tree"

Some of the standard poster sizes are 8.5” x 11," 11” x 17," 18” x 24," 24” x 36,” and 27” x 40."

Smallest  - 11” x 17”


This is the smallest standard poster size they are ideal for street lights, bulletin boards, and generally putting up on businesses without taking up too much room and offending. These also work the best with a minimalist approach to text. Big letters big message.

 Medium  - 18 “ x 24”

A little more information can be displayed on this standard poster size. I would still recommend some minimalism and little text. These posters are mainly seen as small adverts on university residence floors, doctor’s offices, construction walkways and bulletin boards.

 Large24” x 36”

This is one of the most common standard poster size (Super A1). These posters are used for most applications including outside of events, trade shows, and malls. Also widely used for small movie posters delivered to fans and posters for decoration like in University residences and outside a pub or club.  With these types of posters you will be grabbing attention with a large message and you can include further details in small writing so after the message is received people can choose whether to come closer and learn more.


Movie Poster Size

Movie poster size has enjoyed some of the most consistent standards within the industry and have benefited from collectors and the film industry’s standardization.

Most Common movie poster size – Portrait Format Poster - 27” x 40”

This is the most common standard poster size for movies used for advertising movies, collectors, and sometimes basement decoration.

Largest – Bus Stop Poster - 40” x 60”

This is the largest movie standard poster size before moving on to custom sizes they are most commonly used for bus stops.

ppi
In the context of image meta-data, PPI is only relevant for when you're going to print your images (at which point # pixels / PPI setting = physical dimensions of the printed image. –  DA01 Jun 17 '13 at 20:57

billboard prints are set at around 50 ppi never 300ppi. hand held prints are 300ppi small 11x14 and 24x36 posters are printed around 250-300ppi but larger posters around 36x48 are set at 100-200ppi. this has nothing to do with file size but viewing distance. You just don't need a photo quality print that large for ad work. Museum or fine art prints are a different subject. –  danferth Jan 17 '12 at 23:28 


The Tree Poster Design
I'd like to make this natural theme poster design simple, I created a shape of tree by montaging the photographs I captured and collected in the colour spectrum. Tree is probably the biggest plant on earth, a tree also could lighten the theme I chose in the beginning.


Poster

I have selected a background that's framed of dead leaves, and adjusted into very bright black and white colour on purpose to light the tree design piece in the middle, if I choose the back ground with its own colour and tones in the original coloured photography, the tree designed piece will not be able to be seen clearly and also to spot a shape of tree easily. 

I created this entire poster in photoshop, I have selected 6 green coloured photographs from the colour spectrum I created and cropped them into circle shape, and ordered them together to have the look of tree leaves part on the top. At the tree trunk, it is created by ordering the brownish coloured photographs that I took and collected in the colour spectrum. The flowers on the tree are the photographs of different bright coloured flowers like red, purple, yellow and white to give the tree something to lighted the design. 


Final Poster Design
To get a better poster, I have experimented with using different colour mixes to develop the entire poster design process. This time, I have sketched down of what's on my mind that was going to be seen in the poster.
Sketch

A very common logo in the world now: 7 edges marijuana leaf logo, it's been so many arguments between government's laws and people's supportive opinion about marijuana as something positive rather than drugs, and claim of marijuana as a type of plants instead of drugs. I consider this argument standing in between that the fact is marijuana is a type of plants, and it also effects on humans as drug effects and decreases human consciousness. With this two facts of marijuana's characteristics, I have decided to create a poster that tells the audience the both facts of marijuana through the poster.


I have first created a template on Ai Illustrator, a template with many spares to build a "pixelated" look of 7 edges marijuana leaf logo. At the background I have build a stripe-background by rectangle tool and locked the layer as the background layer, I have selected a colour mix that has the rainbow 7 colours order: red, orange, yellow, green, blue, indigo and violet.
Layer 3 as the template for filling images into the squares on photoshop later. Last week, I did the entire montage designing work on Illustrator involving photographs, and the file got 20GB enormous size, eventually it was even hard to reopen the file on Illustrator cause the massive size of the file. Therefore I have concluded that: when editing and working with photographs, use Photoshop is the best choice; when drawing and illustrating work, use Illustrator is the best choice.  Layer 2 is the locked layer of the coloured stripes as the background. 

After I build this template on Illustrator, I saved the file and reopened the file in photoshop; and created a new file in photoshop, size is 11"*17" poster size which is similar to A3 paper size. Selected the colour mode in CMYK for print. 
Then I chose a photograph as the background to interact with the stripes I have created on Illustrator, then place the Ai file on top of the background layer, so that I have the interaction between colour strips and a black and white photograph of plants, and also the template for filling in photographs.
According to the spectrum I have created, I have 6 different colours: green, yellow, red, purple, brown and white. There are 7 edges in the leaf logo, I planned to use 4 colours for the edgers: yellow for the biggest leaf in the middle, and pink for the second biggest leaves in pair, green for the next smaller two leaves and red for the smallest leaves in the bottom. I planned to use the brown colour I have to fill in the tail of the entire leaf logo and white colour to fill in the circle positioned in the middle of the logo.
The outcome of filling into the template in squares has the look I expected, and looks more organised. I also have merged the flayers together into different colour categories. To organise the layers easily rather than have lots of the layers named by numbers which is quite confusing. 
The outcome of the entire poster has the look, but at the pair of green leaves, they seem to disappear cause it's jointed with the green stripe and the, and the yellow leaf in the middle disappears in the yellow stripe. The colour mix of the entire poster might appear a little messy cause of the massive involvement of different more-than-7 colours. Then I planned to adjust the stripes into the colours that I have in the spectrum rather than adding more colours so the entire poster has the same colour theme: I did a little more editing in Illustrator. 
In this poster design, I have used 5 bright colours to build the leaves in the logo: yellow, purple/pink, green, red and white, so according to this order, I have adjusted the strips' colours once again in Illustrator using the 5 bright colours I have mentioned above. I have deleted the template layer I created in Illustrator cause we already have the logo by using that template, the template I built in Illustrator is only used as an aid to create the logo by photographs.
I also have changed the background in photoshop to make the "pixelated" logo look more appearing in the poster. and adjusted the opacity of the Ai stripes to 80%.
I am still developing the poster to get the best and perfect one that I expect to see; I have set the background into black and white photograph to help the logo look more appearing. Also added texts to this poster.

Color Spectrum

Colour is everywhere. We need to set a theme for this project and by using a camera, we need to capture images from the environment to create our own spectrum. Remember colour derives from the spectrum of light, the range of wavelength human can perceive, approximately from 390nanometer to 700nm, it is known as "visible light". After we have completed our full set of colour spectrum, we need to create a design based on our theme and use the colour spectrum. The outcome can be either print or video format. Through this ask we critically analyse harmony and contrast of the colour. 

Colours affect us in numerous ways, both mentally and physically. A strong red color has been shown to raise the blood pressure, while a blue color has a calming effect.

Color Wheel

The color wheel or color circle is the basic tool for combining colors. The first circular color diagram was designed by Sir Isaac Newton in 1666.
The color wheel is designed so that virtually any colors you pick from it will look good together. Over the years, many variations of the basic design have been made, but the most common version is a wheel of 12 colors based on the RYB (or artistic) color model.
Traditionally, there are a number of color combinations that are considered especially pleasing. These are called color harmonies or color chords and they consist of two or more colors with a fixed relation in the color wheel.

In the RYB (or subtractive) color model, the primary colors are red, yellow and blue.


The three secondary colors (green, orange and purple) are created by mixing two primary colors.


Another six tertiary colors are created by mixing primary and secondary colors.



The color circle can be divided into warm and cool colors.
Warm colors are vivid and energetic, and tend to advance in space.
Cool colors give an impression of calm, and create a soothing impression.
White, black and gray are considered to be neutral.


These terms are often used incorrectly, although they describe fairly simple color concepts. If a color is made lighter by adding white, the result is called a tint. If black is added, the darker version is called a shade. And if gray is added, the result is a different tone.









Theme: I set a quite natural theme, and I plan to capture pictures of plants to create my own colour spectrum and the design work based on this theme. 

Types of Plants: I capture photographs of anything that's related to plants, plants could be flowers, trees, grass, leaves or vegetables and fruits. I have collected all of the types I have stated by my camera. Plants are the nature of the earth cause they grow by the dirt, they are alive and living quietly and peacefully. 

Spectrum: I order the photographs I take and collect by looking at the colour wheel as a reference. For example: in the colour wheel, green colour's neighbour is colour yellow, then orange, followed by red, pink, purple and blue. The colour spectrum I have created below follows the colours in colour wheels, it starts with very dark green to light green, followed by bright yellow colour and brownish, red colour until pink to purple. I wasn't really able to capture blue plants, cause blue plants are really rare in everyday life. But I have captured white coloured plants which follows the purple colour on the colour spectrum I create below.

Investigation of the Statement in Colour Psychology by Carl Jung

1. Light and colour can influence how people perceive the area around them. Different light sources affect how the colours of walls and other objects are seen.
This entire universe is darkness, it needs light from the sun to light the things we see, without the sun and light, the world probably would never exist, or it exists in the darkness that nothing can be perceived or seen,  therefore darkness is not considered as a colour. Light is the main element we need to help we see, visualise and perceive by our eyes, without light, there'll be no such thing called "colour" different light source changes the colour itself and to prove this theory, I will conduct a practical research to experiment through photography and provide evidences.

In this experiment, I photographed the changes of colour on the wall in different situations; to prove the first statement, I have chosen to use three different sources of light: home lamp, flash light and natural sun light. The colour of wall involved in this experiment is white colour; and now let's see how the colour of wall changes under different light sources below.

Figure 1
Figure 1 is a photograph taken using home lamp, and the colour of wall appears to be orange, brown or yellowish under home lamp light source.

Figure 2
Figure 2 is a photograph taken using flash light, the wall appears to have two very contrasted colours, black (the shadow of the lamp) and white (the flashed area on the wall) and the tones of the wall colour gets darker which has the "vintage" kind of look.

Figure 3
Figure 3 is a photograph taken using natural sunlight, the colour of the wall stays its own colour-white, although colour changes through different moods of sunlight (such as cloudy weather) 

2. Specific hues of colours seen under natural light may vary when seen under the light from an incandescent (tungsten) light bulb: lighter colours may appear to be more orange or "brownish" and darker colours may appear even darker.
To prove this theory, I will also conduct an experiment by using photography to provide evidences for this statement. In this experiment I plan to photograph the colour change in both black and white coloured dress-up by using different light sources: home lamp and natural sunlight.
Figure 4

Figure 5
 Figure 4 is taken by using home lamp, and the black top colour appears darker and figure 5 was taken by using natural sunlight, and the black top appears to be black and emphasises its own colour.

Figure 6

Figure 7
Figure 6 is taken by using a home lamp, the white coloured top appears to be orange and brownish, but when it's taken under natural sunlight in figure 7, the white colour appears to be its own colour.

3. Light and the colour of an object can affect how one perceives its positioning. If light or shadow, or the colour of the object, masks an object's true contour (outline of a figure) it can appear to be shaped differently from reality.
To help to prove this theory, I photographed using 2 different light condition: when there is low amount of light source such as home lamp at night, and when there is enough light source to see more in the image such as flash light; then I compared and contrasted the two photographs that I've taken and analysed the difference between these 2 photographs.
Figure 8
Figure 8 was taken in a low light condition by using home lamp at night; in this photograph, the shape of a profile appears to be a line that contours the subject. 

Figure 9

Figure 9 was taken in a flash light condition where enough light was provided into this photograph, and the shape and the contour of the subject looks so much different that figure 9 is able to be seen the reality of the subject's profile involved being able to see his eye, nose, lips and ears etc.

4. Objects under a uniform light source will promote better impression of three-dimensional shape.
When light covers the entire object around it, then the less shadow we see, when light covers on the right side of an object, then that object's shadow will appear on its left side. But when an object's covered by light all over, there will be no shadow from the object. To provide evidence, I planned to take photographs of a box under different light source: uniform light and others. 
Figure 10
 Figure 10 was taken by using the incandescent light to be the uniform light, the box in this photograph has less shadow and appears to be more three-dimensional than figure 11.

Figure 11
Figure 11 was taken under the natural sunlight coming from the balcony, the box in this photograph has more shadow than figure 11 as the lights shoots from the balcony and makes the other side have its own shadow. When there is shadow, it is darkness and the darkness is harder to be seen than the lightness. 

Take a look at figure 12, where the flash light exposed too much on the right side of the lamp and makes itself disappear in the brightness of the flashlight, but on the other side of the lamp appears so much darker than the right side and very contrasted between each sides. This is when an object under a NOT uniform light source would appear to be - loose of its own three-dimensional visibility.

When the light has different coloured filters, it changes all the colours of the objects that are involved in the range of the light. For example in figure 13, it is a photograph taken in a room where was covered by purple and red coloured curtains, when light shoots directly through the coloured curtains, the curtain will be a sort of filter for the natural sunlight; the colour of the room filtered by the purple and red curtains appears to have its hues to be red and pink -ish.

5. The colour of an object may affect whether or not it seems to be in motion.
A lot of optical illusion designed work were playing with colours to make the work itself look like it's in motion, optical illusion designed work is also the matter of shapes, lines and other supporting factors to give itself the "motion look" I have experimented with using different mixed colours to explore what kind of colours together  have the motion look.

Figure 14

Figure 15

Figure 14 and figure 15 were both designed by using the type of colour harmony - triad. Triad is the harmony that three colours evenly spaced 120 degree around the colour wheel, the base colour was the yellow colour in figure 14 and 15. 120 degree from the base colour, there were the blue colour in figure 14 and the purple/pink colour in figure 15. The outlook of these colour mixes appear quite of "illusional"

Figure 16

Figure 16 is designed by using the type of colour harmony - complementary. Complementary is the harmony that is opposite on the base colour on the colour wheel. The outlook of this colour mix appears a bit of "illusional"

Figure 17

Figure 18

Figure 17 was designed by the most contrasted colours: black and white/ darkness and lightness. They appear quite "illusional". Figure 18 used a quite bright colour to fill up the white, and the outlook of the "illusional" might have reduced a little from using the mix of black and white.

Figure 19

Figure 20

Figure 19 and 20 used the type of colour harmony - analogous which are the neighbours of the base colour on the colour wheel. The outlook of using analogous harmony is barely hard to see the illusion in the image which reduced a lot of its motion look.

From this experiment, I discovered that when mix two or tree very contrasted colours, it always contains the look of "motion" optical illusion, but when using analogous mix of colour, it may not appear as "illusional" as the very contrasted, bright, energetic colour mixes.
