What defines a primary color?

A primary color is defined as a color that cannot be created by mixing other colors together. Primary colors serve as the foundational colors in the color theory and are used to create a wide spectrum of other colors when they are mixed in various combinations. In traditional color theory, the primary colors are red, blue, and yellow. These colors are distinct because they cannot be derived from the combination of other colors, making them essential for color mixing in art.

Options that suggest mixing colors or refer to ranges on the color wheel do not accurately capture what defines a primary color. For instance, the idea of mixing colors, while central to creating secondary or tertiary colors, does not apply to primary colors themselves. Similarly, references to visual balance or specific color ranges do not pertain to the foundational nature of primary colors.
