The opponent-process theory accounts better for afterimages because it suggests that colors are perceived in opposition to each other. This means that staring at an object in one color for an extended period would cause fatigue in the neurons responsible for processing that color, resulting in an afterimage where the opposite color appears. The trichromatic theory, on the other hand, suggests that color vision is based on the activity of three types of cone cells, which cannot fully explain the phenomenon of afterimages.
