The color wheele represents the 12 most basic colors that are used in everyday life. With the correct combinations, an artist is able to effect how bright or dull a color can appear just by the placement of colors. Everything that is used in art, stems from these 12 colors.
This here is just to show that a bright color next to a dark color appears to be much brighter than when the same color is put next to another light color. Your brain registers the difference in intensity due to the contrast in lightness and darkness.
As you can see here, when a warm color such as orange is placed next to another warm color such as yellow, neither of them seem to be brighter or more intense. However when a warm color like orange is placed next to a cool color such as blue, the orange appears to be more orange and the blue appears to be more blue. This simple color combination gives the illusion that colors are much brighter or more intense, than they really are.
In this example of color interactions, shape and placement play a role in illusion. The way these colors and shapes are placed, appear to move when you stare at them. To prove that this is not done by a computer, stare at one spot and the illusion will stop moving.
This illusion demonstrates how your mind can choose to block out colors that your eye sees. All of this is possible because the gray is the most dominant color that the eye notices so the brain will shut out the pink dots when you concentrate on the center.
This is one of the more simple illusions. Your mind is simply recognizing a familiar shape. However with the black line added in, your mind is playing the illusion that the heart as a sort of orange glow to it. Again this trick has to do with a lighter color being next to a darker color, giving the illusion that the dull yellow is brighter and more of an orange color.
This final illustration is to show more of why color interactions is so important. If we lived in a world without color, as most animals due, a chart such as this one in the news, would not be possible. As humans in modern society, we have assosiated colors to temperatures to help us comprehend informations. As this picture indicates, the warm colors such as red-orange, orange, and yellow, are used to show the hotter regions of california that recieve less percipitation (rain fall) than the areas that are indicated by the cooler regions that are illustrated with green, blue, and purple.
Colors and how they interact with each other can be found in almost everything that is designed by mankind. Colors can provide simple illustrations to help us better understand a concept, or even effect our moods from day to day. The possibilities that color can be used for is virtually limitless. With out color, our minds would see simple grays, black, and white. Thanks to color interactions, our minds our able to separate one object from another similar object. Next time you look at your shirt or a friends shirt, think about the color that is being used, how it is being used, why someone picked that particular color, and why those colors appeal to some but not others, you will begin to realize that color interactions is not just a concept, but a factor in everyday life.
