What defines a complementary color scheme?

• A. Colors next to each other on the color wheel used to create harmony.
• B. A single hue with variations in value and intensity.
• C. Colors opposite each other on the color wheel used to create high contrast.
• D. Colors that are every third hue around the wheel.

Answer: (C)

A complementary color scheme uses colors that are opposite each other on the color wheel, creating strong contrast and lively visual energy. This pairing makes elements stand out and can create a dynamic focal point in a room, such as a bold accent wall or a striking piece of furniture, when balanced with neutrals or muted tones to avoid overwhelming the space. In interior design, complementary schemes are often softened by adjusting value and saturation so the contrast feels intentional rather than harsh.

To contrast, colors next to each other on the wheel form an analogous scheme, which reads as harmonious and cohesive; a single hue with variations in value and intensity is a monochromatic scheme, offering unity with subtle depth; and colors spaced evenly around the wheel in a triadic scheme provide a balanced, playful contrast. The defining feature of complementary schemes is the color opposition that yields high contrast.
