In which direction will yellow-orange shift if yellow is reduced and orange is increased?

Correct answer: Toward orange

The governing concept is proportional colour mixing. Yellow-orange lies between yellow and orange on the colour wheel. If yellow is reduced while orange is increased, the mixture contains a stronger orange influence, so its hue moves toward orange. Therefore, option A is correct. Increasing yellow would move it toward yellow, while yellow-green and red-violet are in different colour-wheel directions and are not produced by this stated adjustment.
