The opponent-process theory suggests that color perception is controlled by the activity of two opponent systems: a blue-yellow mechanism and a red-green mechanism. This theory complements the trichromatic theory, which posits that the eye detects colors through the response rates of three types of cones, but does not suggest these cones are sensitive only to red, green, and blue. The opponent-process theory explains phenomena the trichromatic theory cannot, such as the existence of afterimages and the fact that certain color combinations (like red-green) are never seen together in the same location.
