The general model of color psychology relies on six basic principles: Color may carry a specific meaning. Color meaning is either based in learned meaning or biologically innate meaning. The perception of a color causes evaluation automatically by the person perceiving. The evaluation process forces color-motivated behavior.
Color theory, or more specifically traditional color theory, is a historical body of knowledge describing the behavior of colors, namely in color mixing, color contrast effects, color harmony, color schemes and color symbolism. [1] Modern color theory is generally referred to as color science.
Color symbolism in art, literature, and anthropology is the use of color as a symbol in various cultures and in storytelling. There is great diversity in the use of colors and their associations between cultures [ 1 ] and even within the same culture in different time periods. [ 2 ]
White light decomposes into a spectrum of all colors. There are only two pure colours—blue and yellow; the rest are degrees of these. (Theory of Colours, Volume 3, Paragraph 201/202) [33] Synthesis Just as white light can be decomposed, it can be put back together. Colours recombine to shades of grey. (Theory of Colours, Volume 2, Paragraph ...
White's illusion is a brightness illusion in which certain stripes of a black-and-white grating are replaced by gray rectangles (see the figure). Both of the gray bars of A and B have the same color, luminance, and opacity. The brightness of the gray rectangles appears to be closer to the brightness of the top and bottom bordering stripes.
Johann Wolfgang von Goethe writes in 1810 that a grey image on a black background appears much brighter than the same on white. [2] And Johannes Peter Müller notes the same in 1838 and also that a strip of grey on a brightly coloured field appears to be tinted ever so slightly in the contrasting colour.
Unique hue is a term used in perceptual psychology of color vision and generally applied to the purest hues of blue, green, yellow and red. The proponents of the opponent process theory believe that these hues cannot be described as a mixture of other hues, and are therefore pure, whereas all other hues are composite. [ 1 ]
An important goal of this adjustment is to render specific colors – particularly neutral colors like white or grey – correctly. Hence, the general method is sometimes called gray balance, neutral balance, or white balance. Color balance changes the overall mixture of colors in an image and is used for color correction.
