Three-color matching chart pattern

Quick answer：

Three-color matching charts are visual tools used in graphic design and fashion to demonstrate how different colors can be combined. They usually consist of a grid or a layout with specific color palettes that suggest complementary or contrasting color combinations. Patterns, in this context, refer to the arrangement or design of these colors in a repetitive or decorative manner. The knowledge of color theory is essential when creating such charts to ensure aesthetic harmony and effective communication of the intended message.
