If yellow is first mixed into red and then a very small amount of blue is added, what will be the likely tendency of the final colour?

Correct answer: A slightly subdued or muddy orange

Red mixed with yellow first produces an orange family colour. Adding a small amount of blue introduces a component opposing orange on the colour wheel, so the mixture loses some saturation and tends toward a duller, muted or muddy orange. It will not become pure green or pure violet because the proportions are dominated by red and yellow, and the added blue is only a small amount. The result can vary with pigment properties.
