The trichromatic theory explains the first stage of color processing, which involves the cones in the retina responding to different wavelengths of light. The opponent-process theory explains the second stage of processing, which occurs in the ganglion cells of the optic nerve, where information from the cones is combined and certain color pairs are processed in opposition to each other. Therefore, the two theories do not conflict but rather describe different stages of color processing.
