Tertiary colors are created by combining which of the following?

Tertiary colors are formed by mixing primary colors with adjacent secondary colors on the color wheel. Primary colors include red, blue, and yellow, while secondary colors are created by mixing these primary colors together (e.g., red + blue = purple). For instance, mixing blue (a primary color) with green (a secondary color, made from blue and yellow) results in the tertiary color blue-green. This process illustrates how tertiary colors are a blend of the foundational primary colors with the intermediate secondary colors, resulting in a richer palette and greater variety in color perception.
