Ewald Hering's opponent-process theory suggests that color vision is controlled by three opposing systems, explaining phenomena like afterimages by proposing that certain colors oppose each other (e.g., red-green, blue-yellow). This theory contrasts with the trichromatic theory, which involves three types of color receptors without the concept of opposing colors.
