Generate complementary, analogous, triadic and monochromatic palettes from any starting colour, plus a full lightness ramp suitable for a design system.
Getting started
Choose a base colour that represents your brand or design direction.
Pick a harmony rule — complementary, analogous, triadic or monochromatic.
Copy any swatch, or take the full lightness ramp for a design system scale.
Why it helps
Harmony rules are calculated in a perceptually uniform space, so results look balanced rather than merely mathematically correct.
The lightness ramp gives a complete 50-to-950 scale ready to drop into a design system.
Every swatch shows its HEX value and copies with one click.
In practice
Building a brand palette from a single agreed primary colour.
Generating a complete tonal scale for a design system.
Finding an accent colour that works with an existing brand hue.
Everything people ask most about the colour palette generator, answered plainly.
