Which of the following is an example of a tertiary color?

A tertiary color is created by mixing a primary color with a secondary color. In the traditional color wheel, the primary colors are red, blue, and yellow, while the secondary colors are green, orange, and purple. By combining a primary and a secondary color, tertiary colors are formed, which include names like red-orange, yellow-green, blue-purple, etc.

Plum is a good example of a tertiary color because it is typically a mix of red (primary) and purple (a secondary color). This combination results in a shade that is not merely a primary or a secondary color but sits in the in-between range, thus classifying it as a tertiary color.

In contrast, colors like orange and green are secondary colors, and turquoise is generally viewed as a variation of blue, which stems mostly from primary colors rather than a mix that fits the definition of tertiary. Understanding these classifications helps in mastering color theory, essential for any esthetics professional dealing with color applications in beauty treatments.
