The matching of two colors

Quick answer：

The matching of two colors in design refers to the combination of hues that are aesthetically pleasing and harmonious. It involves principles such as complementary colors, analogous colors, and triadic colors. Complementary colors are pairs that contrast each other, like red and green. Analogous colors are next to each other on the color wheel and work well together, such as red, red-orange, and orange. Triadic colors are evenly spaced on the color wheel and offer a vibrant combination. Color theory and the understanding of color psychology play a crucial role in effective color matching.
