About the Color Palette Generator

A free, browser-based tool that applies color theory to turn any base color into a complete, ready-to-use palette.

What it is

The Color Palette Generator takes a single base color and applies one of six classic color harmony rules to produce a palette of five coordinated colors. For each color you get the HEX, RGB, and HSL values — all copyable with one click. The tool runs entirely in your browser; nothing is uploaded or stored.

Harmony modes

Complementary

Pairs your base color with its opposite on the color wheel — maximum contrast, great for highlights and CTAs.

Analogous

Three neighboring hues spaced 15–30° apart — calm, cohesive, ideal for professional UI themes.

Triadic

Three colors evenly spaced at 120° — vibrant and balanced, popular in illustration and branding.

Split-Complementary

Base color plus the two hues flanking its complement — high contrast with less tension than complementary.

Tetradic (Square)

Four hues evenly spaced at 90° — richly varied, best used with one dominant and others as accents.

Monochromatic

Shades and tints of a single hue — minimal, elegant, and easy to work with for any skill level.
