What results when red-violet dominates a mixture with yellow-green?

Correct answer: A muted reddish violet or warm neutral

The governing concept is the effect of dominance in a complementary mixture. Red-violet and yellow-green oppose each other, so adding both reduces saturation rather than producing a brighter pure hue. Because red-violet is dominant, the remaining colour bias is reddish-violet, although the mixture may approach a warm neutral if enough complement is present. Option A captures both possibilities. The other options incorrectly predict a bright original colour, cyan, or white.
