Which mixture can be used as a starting point for a light warm skin-like colour?

Correct answer: Add a little red and yellow to white

The governing concept is building a light warm tint from a light base and warm hues. Starting with white and adding small amounts of red and yellow introduces warmth while preserving a high value, producing a useful base for a skin-like colour. The exact mixture is not universal because lighting, complexion, pigment strength, and the desired result matter. Blue-black combinations are cool and dark, while green-violet is not a suitable warm light starting point.
