Complementary Color Finder: what to know
The complementary color finder shows the color directly opposite yours on the color wheel, 180 degrees around. Complementary pairs such as blue and orange or purple and yellow-green give the strongest hue contrast possible, so they make each other look more vivid when placed side by side.
That strength is useful for calls to action, highlights and sports or brand identities that need to pop, but it can be tiring in large equal areas. A common approach is to use one color as the main color and its complement as a small accent.
The finder rotates the hue in OKLCH and keeps your color's lightness and chroma, so the complement looks equally light and strong: #DB2777 pink pairs with #009281 teal. Painters using the RYB wheel get different pairs, such as red with green instead of red with cyan.
Popular uses
- Choosing a call-to-action color that stands out
- Adding an accent to a mostly single-color design
- Creating high-energy posters and sports branding
- Picking a highlight color for charts
Tips for the best result
- Give the two colors unequal areas, around 80/20, so they don't fight.
- Vibrating edges between saturated complements are hard to read; don't set text in one on the other.
- Try a lighter tint of the complement for backgrounds and the full color for accents.
