Oklahoma PMU Practice Exam

Warm colors convey energy and light, and on the color wheel they sit together in the red–orange–yellow range. The material presents the warm trio as red, orange, yellow, which is the standard order used there. That makes this set the best fit for listing warm colors. The other options either include cool colors like blue, violet, or green, or mix the warm colors in a nonstandard order, which the material doesn’t use. So the correct listing is red, orange, yellow.
