How are tertiary colors created?

Tertiary colors are created by mixing a primary color with a secondary color. This process enriches the color palette by producing hues that lie between the primary and secondary colors on the color wheel. For example, mixing blue (a primary color) with green (a secondary color) results in a bluish-green tertiary color known as teal. This blending expands the range of colors available for artistic and design purposes, allowing for more nuanced and varied color combinations.

The other options do not accurately describe the process of creating tertiary colors. Mixing two primary colors results in a secondary color, adding white to a primary color creates a tint, and mixing two secondary colors would yield a different outcome that does not specifically produce tertiary colors. Understanding this distinction is essential for anyone studying graphic communication and color theory.
