Which condition is best for obtaining a clean green?

Answer and explanation

Correct answer: Yellow and blue should contain no red contamination

The governing concept is purity of pigment mixtures. Green is produced by combining yellow and blue. If either component contains red, that unwanted colour can interact with the mixture and reduce the green’s brightness, often making it dull or brownish. Clean yellow and blue therefore give the best chance of a clear green, so option A is correct. Black, orange or already muddy pigments introduce impurities and lower colour intensity.
