The trichromatic theory of color vision, also known as the Young-Helmholtz theory, applies to the retina and states that there are three types of color receptors (cones) that are sensitive to red, green, and blue wavelengths. The opponent-process theory, on the other hand, explains what happens in the optic pathways and the brain after information leaves the eye, and suggests that there are three pairs of opposing color channels - red/green, blue/yellow, and black/white- which work together to create the perception of all possible colors.
