    Best for: High-impact designs, CTAs, logos

    Split-complementary

    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.

    Best for: Rich, diverse color schemes
