In an afterimage experiment, which colour may appear on a white surface after staring at red for a long time?

Answer and explanation

Correct answer: Green or cyan-like

The governing concept is visual adaptation and opponent-colour response. After the eyes stare at red for a long period, the red-sensitive response becomes temporarily fatigued. When the gaze shifts to a white surface, the less-adapted opposing response can be noticed as a greenish or cyan-like afterimage. Therefore option A is correct; the original red and nearby warm colours are not the expected opponent effect.
