If a little red is added to yellow, which colour family will the new colour approach?

Correct answer: Orange

The governing concept is colour mixing and the position of related hues. Red and yellow are primary colours that combine toward orange. Because only a little red is added to yellow, the mixture will remain yellow-biased but move toward the orange family, often appearing yellow-orange. Green would require yellow and blue, violet would involve red and blue, and blue is not produced by this combination. Hence, option C is correct.
