How to match 4 colors

Quick answer：

Matching four colors in a harmonious way involves understanding color theory and principles of color harmony. You can use complementary colors, analogous colors, split-complementary colors, or triadic color schemes. Complementary colors are pairs that are opposite on the color wheel, creating a striking contrast. Analogous colors are next to each other on the wheel, offering a more harmonious blend. Split-complementary colors involve using two complementary colors and the colors adjacent to them. Triadic colors are evenly spaced around the color wheel, creating a vibrant and dynamic palette. It's also important to consider the context, such as the material, texture, and lighting of the items being colored.
