What are complementary colors?

Complementary colors are two colors that sit directly opposite each other on the color wheel, such as red and green, blue and orange, or yellow and purple. When placed next to each other, they create the highest possible contrast.

When should I use a complementary color scheme?

Use complementary schemes for high-impact designs where you want to draw attention to a specific element — like a CTA button or hero headline. They work well for sports brands, retail, and anywhere you want energy and visual tension.

Are complementary colors always a good choice?

Not always. Full-saturation complementary pairs can feel jarring if both colors are used in equal amounts. A common technique is to use one color dominant and the other as an accent at lower saturation or in smaller areas.

How is a complementary color calculated?

In HSL color space, the complementary color is calculated by adding 180 degrees to the hue of the original color. The saturation and lightness values stay the same, only the hue is shifted by half of the full 360-degree wheel.

What is a Complementary Color Scheme?

A complementary color scheme uses two colors that are opposite each other on the color wheel. This creates a high-contrast, vibrant look that can be very eye-catching and dynamic.

Complementary colors naturally enhance each other's intensity when placed side by side. This creates a strong visual impact and can help draw attention to key elements in your design. However, this high contrast can also be jarring if overused, which is why complementary schemes are often used with one color as dominant and the other as an accent.

Tips for Using Complementary Color Schemes

Use the 80/20 rule: Use one color as the dominant color (about 80% of your design) and the complementary color as an accent (about 20%).
Add neutrals: Incorporate neutral colors like white, black, or gray to provide visual rest and prevent the complementary colors from competing too much.
Consider using tints and shades: Using lighter or darker versions of your complementary colors can provide more flexibility and subtlety in your design.
Use for emphasis: Complementary colors are excellent for highlighting important elements or creating focal points in your design.
Test for accessibility: The high contrast of complementary colors can be great for readability, but always check that text remains legible.
