Opponent-process theory provides a more comprehensive explanation for color afterimages than trichromatic theory. This is because it accounts for the way colors are perceived in opposing pairs, which explains why staring at one color can lead to the perception of its opposite color in an afterimage. Trichromatic theory, focusing on the three types of color receptors in the eye, does not directly explain this phenomenon.
