Quizplus · Accepted Answer

The professor has demonstrated afterimages, which occur when the visual system adapts to a color and then produces an image in the complementary or opposite color when the original color is removed. Staring at the solid green square caused Juan's eyes to adapt to the green color, and when the white screen was shown, his visual system produced an afterimage of the complementary color, which is red.
