Accuracy & limitations

Harmony schemes are hue arithmetic on the color wheel. They tell you which hues relate to each other, and nothing about whether the palette suits your project or passes contrast.

Harmony schemes are hue rotations on the color wheel. They tell you which hues relate, not whether the resulting palette suits your project.
Generated colors carry no accessibility guarantee. Check any pair you plan to use for text in the contrast checker.
Saturation and lightness are held near the base color, so a very light or very dark input produces a correspondingly narrow palette.
Hue rotation in HSL is not perceptually uniform — a 120-degree step does not feel equally large everywhere on the wheel.

Frequently asked questions

Which harmony should I use?

Analogous palettes feel calm, complementary palettes feel energetic, and triadic palettes feel balanced and vibrant.

How are the colors calculated?

The tool rotates the base hue on the color wheel and adjusts lightness or saturation to build each scheme.

Can I lock a color I like?

Copy any swatch you want to keep, then generate again around a new base for more options.

How many colors per palette?

It depends on the harmony — from two for complementary up to five for monochromatic and tonal sets.

Are palettes free to use?

Yes. The colors you generate are yours to use in any personal or commercial project.
