Why is practical testing of secondary colours necessary alongside an ideal colour wheel?

Answer and explanation

Correct answer: Real pigments may behave differently from ideal mixtures

The governing concept is the difference between theoretical colour relationships and physical pigment behaviour. A colour wheel predicts useful relationships, but real pigments vary in tinting strength, transparency, undertone and absorption; mixtures may therefore look duller or shift in hue. Option A is correct. The wheel remains useful, and practical testing supplements rather than rejects theory. The other choices make absolute or false claims.
