Why can the same orange appear different on grey and blue backgrounds?

Answer and explanation

Correct answer: Surrounding colours alter its perceived brightness and temperature

The governing concept is contextual colour perception, especially simultaneous and complementary contrast. The orange pigment remains physically the same, but the surrounding field changes how the eye and brain judge its saturation, brightness, and warmth. A blue background, being broadly complementary to orange, may make it seem stronger or warmer, while grey provides a more neutral comparison. Option A is correct; no chemical or physical mixing is required.
