What are three colors that are equidistant on the color wheel called?

The term used to describe three colors that are equidistant on the color wheel is "triadic colors." This concept arises from color theory, where the wheel is divided into sections representing primary, secondary, and tertiary colors. A triadic color scheme is one that employs three colors that form a triangle on the color wheel, ensuring balance and vibrancy in a design. This combination is often used because it creates a harmonious visual effect while allowing for contrast and diversity in imagery.

By contrast, tetradic colors refer to a group of four colors that are equally spaced in a rectangular formation on the color wheel, which is not the case for three-color schemes. Square colors also refer to a four-color scheme but arranged in a square format on the wheel. Split complementary colors involve one base color and the two colors adjacent to its complementary color, which does not create an equidistant relationship. Thus, triadic colors distinctly characterize the requested set of three equidistant colors effectively.
