Which pair of colors forms a secondary color on the color wheel?

• A. Red and Blue
• B. Red and Yellow
• C. Blue and Yellow
• D. Yellow and Green

Answer: (C)

Mixing two primary colors creates a secondary color. On the pigment color wheel used in PMU, the primaries are red, blue, and yellow. When you combine blue with yellow, you get green, which is a secondary color. So blue and yellow form a secondary color. The other pairings produce purple (red + blue), orange (red + yellow), or a lighter shade of green (yellow + green), none of which are the standard secondary colors on the pigment wheel.
