A 'three color matching scheme' refers to a design approach that involves selecting and combining three colors to create a harmonious and aesthetically pleasing composition. This concept is commonly used in various fields such as fashion, interior design, and graphic design. The key to successful color matching lies in understanding color theory, including color harmony, contrast, and complementarity. Color schemes can be categorized into primary (complementary), secondary (analogous), and tertiary (split-complementary) groups.
