Any pair of complementary colors are opposite to each other and satisfy each other. When they are compared at the same time, they can make each other reach the maximum significance, but when they are mixed together, they cancel each other out and become a grayish black. The mutually satisfying factors in complementary colors constitute a concise whole, so they have unique performance value in colors.

Complementary colors can block each other. Complementary colors in colors will reduce color purity and turn gray. Generally, you don't need complementary colors when painting.

However, when the two colors are complementary to each other, when one color occupies a much larger area than the other, the contrast of the picture can be enhanced and the picture can be eye-catching. The juxtaposition of complementary colors will cause a strong color contrast, which will make the red one redder and the green one greener.
