What characterizes complementary colors on the color wheel?

Complementary colors are characterized by being located directly opposite one another on the color wheel. This relationship creates a strong visual contrast when these colors are placed side by side, enhancing each other's intensity. For example, red and green are complementary colors; when used together, they evoke a dynamic and vibrant effect.

The distinction of complementary colors being opposites is important in color theory. When mixed, complementary colors tend to neutralize each other, usually resulting in a gray or brown tone, but their primary definition focuses on their positions on the color wheel. Understanding this aspect is crucial for artists and designers in creating visual interest and harmony in their work.

In contrast, the other options describe different relationships or characteristics of colors that do not define complementary colors specifically. For instance, colors that are next to each other on the wheel are referred to as analogous colors, which share similar hues and create a more harmonious effect rather than a contrasting one.
