• A. 4
• B. 8
• C. 6
• D. 10

Answer: (C)

The correct answer regarding the number of tertiary colors on the color wheel is six. Tertiary colors are created by mixing a primary color with a secondary color. There are three primary colors: red, blue, and yellow; and three secondary colors: green, orange, and purple. When combined, each primary color with a neighboring secondary color produces a tertiary color.

For example, mixing red (a primary color) with orange (a secondary color) creates red-orange, and mixing blue (a primary color) with green (a secondary color) results in blue-green. This pattern continues for all primary and secondary color combinations. As there are three primary colors and three secondary colors adjacent to them, you ultimately end up with a total of six distinct tertiary colors: red-orange, yellow-orange, yellow-green, blue-green, blue-purple, and red-purple.

In terms of color theory, recognizing the role and formation of tertiary colors is essential for achieving a harmonious color palette and understanding how colors interact with one another in design.
