According to opponent-process theory, the visual system processes color in terms of opposing pairs, such as red-green and blue-yellow. When Lynn was in the red light, her visual system became adapted to the presence of red light, causing her to perceive green as the opposite color when she came out of the room. This temporary afterimage is consistent with the opponent-process theory.
