Are your colors too loud, or do they “fight” with each other for attention? Are all your colors bright, but none of them “pop”?
Colors are relative— A shade appears red when it’s “redder” than its neighbor, and bright when it’s brighter than its neighbor.
If you want to make something “pop”, make it really look bright red – drain the red out of the environment around it. Or put the opposite color on the color wheel into the environment:
Red – Green
Blue – Orange
Yellow – Purple
Each one of the colors makes the other stand out.
