color matching

Quick answer：

Color matching is the process of selecting colors that harmonize well together. It is a fundamental concept in design, fashion, and art, where colors are combined to create a visually pleasing effect. In the context of design, color matching involves understanding color theory, which is the study of how colors interact with each other. This includes color harmony, which is the concept of using colors that complement one another, and color contrast, which is the use of colors that stand out against each other to create emphasis.
