The trichromatic theory explains color vision at the level of the photoreceptors in the retina, where three types of cones respond to short, medium, or long wavelengths of light. The opponent-process theory, on the other hand, describes how color information is processed beyond the photoreceptors, particularly in the neurons of the retina and the brain, where colors are perceived in opposing pairs (blue-yellow, red-green, and black-white). This means that the opponent-process theory accounts for neuron activity occurring outside of the first level of the visual system, which is primarily concerned with the initial detection of light and color by the photoreceptors.
