In terms of color theory, there can be many ways to find matching colors, such as choosing complementary, analogous and triadic colors from the color wheel. Complementary colors are those that are opposite each other on this wheel, such as the colors blue and orange. Matching colors can entail choosing analogous colors that are next to one another on the wheel as well, like light and dark blue.
Choosing triadic colors from the wheel entails picking three colors that form an equilateral triangle on the wheel. By using the color wheel, it is also possible to pick other color schemes, including tetradic and split complement colors. Tetradic colors are two pairs of complementary colors, and split complement color is one specific color and two colors that are adjacent to it.
A color wheel is a circular chart that contains the primary, secondary and tertiary colors. The primary colors are red, yellow and blue, and the secondary colors are purple, green and orange. The tertiary colors are the combinations of the secondary colors.
