The trichromatic theory explains how color vision works at the level of the cones in the retina, where three types of cone cells are responsible for detecting different wavelengths of light. The opponent-process theory explains how color vision works in the ganglion cells and visual cortex, where cells respond to contrasting pairs of colors (red-green, blue-yellow, and black-white) and create the perception of color.
