Complement

A color and its opposite on the color wheel, +180 degrees of hue. High contrast.

Best for: High-impact designs, CTAs, logos

Split-complementary

A color and two adjacent to its complement, +/-30 degrees of hue from the value opposite the main color. Bold like a straight complement, but more versatile.

Best for: Vibrant yet balanced layouts

Triadic

Three colors spaced evenly along the color wheel, each 120 degrees of hue apart. Best to allow one color to dominate and use the others as accents.

Best for: Playful, energetic designs

Analogous

Three colors of the same luminance and saturation with hues that are adjacent on the color wheel, 30 degrees apart. Smooth transitions.

Best for: Nature-inspired, calming interfaces

Monochromatic

Three colors of the same hue with luminance values +/-50%. Subtle and refined.

Best for: Minimalist, sophisticated designs

Tetradic

Two sets of complementary colors, separated by 60 degrees of hue.
