Why does colour clarity often decrease when all three primary pigments are increasingly present in a mixture?

Answer and explanation

Correct answer: More wavelengths begin to be absorbed

This result follows the subtractive model of pigment mixing. Each primary pigment absorbs part of the incoming white light; when all three are present in increasing amounts, a wider range of wavelengths is absorbed. Less selective light is reflected to the eye, so the mixture can lose brilliance and look neutral or muddy. Therefore option B is correct, while the other choices do not explain the optical effect.
