Which quality should primary colours have to produce a clean secondary colour?

Answer and explanation

Correct answer: They should be free from contamination by the third primary colour

Clean secondary colours require reasonably pure primary paints. The two paints being mixed should not contain a noticeable amount of the third primary colour; otherwise unwanted colour contamination makes the result dull or muddy. Thus option A is correct. Black, excessive lightness and old dryness do not guarantee purity and may reduce the brightness or workability of the mixture.
