Designers can use color theory to determine which colors look good together. This is both a science and art of color matching. The color theory describes how colors mix, match, and contrast, and the visual effects they have on humans.

There are three main categories of colors in color theory: primaries, secondary colors, and tertiary colors.

Creating color harmony is the art of combining colors together. They are used by artists and designers in the creation of certain looks. Using the principles of color combinations, you can use a color wheel to find color harmonies. To find colors that work well together, the color combinations are arranged relative to each other.

Color wheels come in two types. An RYB color wheel, which is usually used by artists to combine paint colors, is helpful for combining red, yellow, and blue colors. Additionally, there is the RGB color wheel, which refers to mixing colors on a computer or TV screen..
