What are Complementary Colors?

Complementary colors sit directly opposite each other on the color wheel—red and green, blue and orange, yellow and purple. This 180-degree relationship creates maximum chromatic contrast, making each color appear more vibrant when placed together.

The effect is electrifying. Complementary pairs create visual tension and energy that draws attention. Sports teams, food brands, and attention-demanding designs rely on this principle for instant impact.

Why Use Complementary Palettes?

When you need elements to pop, complementary colors deliver. Call-to-action buttons against their complementary background achieve maximum visibility. Feature callouts demand attention. Error and success states clearly differentiate.

The contrast also creates visual balance. Each color intensifies the other, neither appearing washed out or dominant. It's nature's own palette—think of red berries against green leaves or orange sunsets over blue water.

How It Works

Start with your primary color. Rotate 180° on the color wheel (add 180 to the hue value) to find its complement.

Primary: hsl(200, 80%, 50%) — Blue Complement: hsl(20, 80%, 50%) — Orange

For practical palettes, work with tints and shades of each color rather than using them at full saturation. This prevents visual fatigue while maintaining complementary energy.
