The method of complementary color matching

Quick answer：

Complementary color matching involves selecting colors that are directly opposite each other on the color wheel. These colors, when combined, cancel each other out and create a sense of balance and harmony. This technique is often used in design, fashion, and art to create a striking contrast. In color theory, complementary colors are divided into primary and secondary groups, with primary complements being directly opposite on the wheel and secondary complements being the two colors adjacent to the primary complement.
