Quizplus · Accepted Answer

The trichromatic theory explains color vision at the level of the retina, where three types of cones respond to different wavelengths of light. The opponent-process theory explains color vision at the level of the visual processing pathways in the brain, where signals from the cones are combined and then further processed into signals for pairs of opposing colors (red vs. green, blue vs. yellow, black vs. white). Therefore, the two theories are not in conflict because they correspond to different stages of visual processing.
