How it works
Each scheme is built by rotating your base colour’s hue on the colour wheel while keeping its saturation and lightness: complementary is +180°, triadic is ±120°, analogous is ±30°, split-complementary is +150°/+210°, and tetradic adds a fourth at +60°/+240°. Monochromatic instead holds the hue and steps the lightness. Click any swatch to copy its hex — all computed locally.
