If an orange mixture contains twice as much red as yellow, toward which colour will it lean?

Correct answer: Toward red

The governing concept is colour bias in a mixture: the component present in the greater proportion usually has the stronger visual influence. Orange is made from red and yellow. If the mixture contains twice as much red as yellow, its hue will shift away from balanced orange toward red-orange, so option C is correct. It would lean toward yellow only when yellow predominated; green and blue are not the stated components of this mixture.
