Instead of Newton's division of sunshine into seven rays, Schopenhauer claimed that color was a division of the eye's retina into two complementary parts. Like the Delphic Oracle , Copernicus , and Kant , Schopenhauer concentrated on the subjective rather than the objective, on the observer's experience rather than the observed object.
Blue–red contrast demonstrating depth perception effects 3 Layers of depths "Rivers, Valleys & Mountains". Chromostereopsis is a visual illusion whereby the impression of depth is conveyed in two-dimensional color images, usually of red–blue or red–green colors, but can also be perceived with red–grey or blue–grey images.

Color psychology is the study of colors and hues as a determinant of human behavior. Color influences perceptions that are not obvious, such as the taste of food. Colors have qualities that may cause certain emotions in people. [1] How color influences individuals may differ depending on age, gender, and culture. [2]
You can use a few online tools to check color contrasts, including: the WebAIM online contrast checker, or the WhoCanUse site, or Snook's Color Contrast Check. Several other tools exist on the web, but check if they are up-to-date before using them. Several tools are based on WCAG 1.0's algorithm, while the reference is now WCAG 2.0's algorithm.
From a physiological point of view, the LMS color space describes a more fundamental level of human visual response, so it makes more sense to define the physiopsychological XYZ by LMS, rather than the other way around. A set of physiologically-based LMS functions were proposed by Stockman & Sharpe in 2000.
In Chevreul's 1839 book The principles of harmony and contrast of colours, [11] he introduced the law of color contrast, stating that colors that appear together (spatially or temporally) will be altered as if mixed with the complementary color of the other color, functionally boosting the color contrast between them. For example, a piece of ...
While this theory with 4 unique hues was initially considered contradictory to the Young-Helmholtz trichromatic theory's three primary colors, the two theories were reconciled theoretically by Erwin Schrödinger [7] and the later discovery of color-opponent cells in the retina and lateral geniculate nucleus (LGN) related the two theories ...
