What is formed by mixing a primary color with an adjacent secondary color on the color wheel?

When a primary color is mixed with an adjacent secondary color on the color wheel, the result is referred to as a tertiary color. Tertiary colors are created through the blending of a primary color with a secondary color that is directly next to it. For example, mixing yellow (a primary color) with orange (a secondary color that is next to yellow) will create a color known as yellow-orange, which is a tertiary color.

This concept is essential for understanding color theory and how different hues interact with one another. Tertiary colors typically have more complexity than primary or secondary colors, adding depth and variety to color palettes. Recognizing this relationship helps colorists in their work, as they select and mix colors for hair treatments, ensuring the results are aesthetically pleasing and harmonious. Understanding the formation of tertiary colors gives practitioners a stronger foundation for creating customized color results.
