Question

Quizplus · Accepted Answer

According to the opponent process theory, staring at a black-and-white photograph for a long time can cause fatigue in the color-sensitive cells in the retina, causing an afterimage in the complementary color. In this case, staring at a red frame would cause fatigue in the green-sensitive cells, causing an afterimage in green. Therefore, the rectangle would appear to be green.
