Which is the most controlled way to create a light peach colour?

Correct answer: Add a little red and yellow to white

The governing concept is controlled colour mixing by starting with a light base and adding stronger hues in small quantities. A white base with a little red and yellow produces a light, warm peach; the proportions can be adjusted gradually until the desired result is reached. Therefore, option A is correct. Black added to red makes a dark, dull mixture, blue and yellow generally move toward green, and violet mixed with green tends toward a muted neutral rather than peach. Adding small amounts to white gives the best control.
