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.
Close-up of a trichromatic in-line shadow mask CRT display, which creates most visible colors through combinations and different levels of the three primary colors: red, green and blue Trichromacy or trichromatism is the possession of three independent channels for conveying color information, derived from the three different types of cone ...
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 usually exerts its influence automatically. Color meaning and effect has to do with context as well. [12]
A related type of chromatophore, the leucophore, is found in some fish, in particular in the tapetum lucidum. Like iridophores, they utilize crystalline purines (often guanine) to reflect light. Unlike iridophores, leucophores have more organized crystals that reduce diffraction. Given a source of white light, they produce a white shine.
Colors and the laws by which they appear reside within the eye. The external cause of color is a stimulus which excites the retina and separates its polarity. Goethe had organized color into three classes: physiological, physical, and chemical. He proposed that the external causes of color are physical colors and chemical colors. [16] [17]

Thomas Young and Hermann von Helmholtz assumed that the eye's retina consists of three different kinds of light receptors for red, green and blue.. The Young–Helmholtz theory (based on the work of Thomas Young and Hermann von Helmholtz in the 19th century), also known as the trichromatic theory, is a theory of trichromatic color vision – the manner in which the visual system gives rise to ...
The color that is seen by our eyes is that of the light not absorbed by the reflecting object within a certain wavelength spectrum of visible light. The chromophore indicates a region in the molecule where the energy difference between two separate molecular orbitals falls within the range of the visible spectrum (or in informal contexts, the ...
