Color Palette Generator

A free online utility tool that generate color schemes: monochromatic, complementary, and more. Simple, fast, and completely private — just open and use. Building harmonious color palettes is a core step in brand design, UI theming, and data-visualization styling. Designers need complementary, analogous, triadic, and monochromatic schemes derived from a single seed color, but iterating through color-theory relationships manually is slow and requires deep knowledge of the HSL color wheel. Pick a base color via the picker or hex input, then choose from five harmony rules — complementary, analogous, triadic, tetradic, and monochromatic — to generate a coordinated five-swatch palette. Each swatch copies its hex code on click. Pick a base color using the color picker or enter a hex value, then choose a harmony type (complementary, analogous, triadic, tetradic, or monochromatic). Click any swatch to copy its hex code. All palette generation happens locally. No colors or preferences are stored or tracked.
