What type of color is yellow-green?

Yellow-green is classified as a tertiary color because it is created by mixing a primary color, yellow, with a secondary color, green. In the color wheel, tertiary colors are formed by combining a primary color with a neighboring secondary color, resulting in a hue that is not purely one or the other. This distinction is crucial to understanding color theory, as it helps in recognizing how different colors relate to one another and how they can be created and used in various applications such as hair coloring.

Tertiary colors serve an important role by expanding the color palette and allowing for a wider range of shades and tones, which can be vital for achieving the desired results in hair coloring techniques.
