E) complementary colors always look complementary.

Question

Quizplus · Accepted Answer

Color constancy is the ability of the human visual system to perceive colors of objects consistently despite changes in the illumination conditions. This means that even if the wavelengths of the light reflecting off an object change, our brain perceives the same color for that object. This is important for accurate perception of color in different lighting conditions. Therefore, the best choice is D, which describes how color constancy ensures that an object appears to be the same color despite changes in the wavelengths of light that it is reflecting.
