The opponent process theory suggests that color vision is based on three pairs of opposing color receptors: blue/yellow, red/green, and black/white. Neurons that respond to one color in each pair inhibit their partner neurons, creating the sensation of color. This theory explains how we perceive afterimages, where one color will appear to linger after staring at an image. The trichromatic theory, on the other hand, suggests that color vision is based on the activation of three different types of cones in the retina, each sensitive to a different range of wavelengths.
