Why does the colour become muddy when all three primary colours are overmixed?

Answer and explanation

Correct answer: Multiple pigments absorb more light together and reduce colour purity

The governing concept is subtractive mixing of pigments. Yellow, red and blue pigments each absorb selected parts of white light; when all three are mixed excessively, their combined absorption increases and the reflected light becomes less specific. Saturation and brightness therefore fall, producing a dull brownish or greyish appearance called muddiness. Paper absorption, brush size and water content do not explain this optical result. Thus, option C correctly states the reason.
