What is generally obtained by mixing complementary colours?

Correct answer: A muted brown or grey colour

The governing concept is complementary colour neutralisation. Complementary colours lie opposite each other on the colour wheel, such as red and green or blue and orange. When pigment complements are mixed, they reduce each other’s saturation and usually produce a dull, muted brown, grey, or neutral-looking colour. Thus option A is correct. They do not normally create a bright primary colour, pure white, or one fixed result such as only pink.
