Which of the following colors cannot be created by mixing other pigments?

• A. Green
• B. Orange
• C. Red
• D. Purple

Answer: (C)

Red is considered a primary color in the traditional color wheel used in art and design, which means it cannot be produced by mixing other pigments. Primary colors, which include red, blue, and yellow, serve as the foundation for creating all other colors.

When you mix primary colors together, you can create secondary colors: red mixed with yellow yields orange, and red mixed with blue creates purple. Green is formed by mixing yellow and blue. Therefore, red stands apart from these other colors because it is not derived from a combination of other pigments, highlighting its unique status as a fundamental color essential for color mixing and theory.
