Primary, secondary, and semantic surfaces are mapped onto a small interface so you can judge the system before moving it into a design system.

Frequently Asked Questions

The generator is built for designers and frontend teams that need usable color systems, not isolated swatches.

How does the brand palette generator build a full system from one color?

The generator starts from your seed color, maps it onto a harmony rule, then derives semantic roles such as primary, secondary, accent, surface, background, text, and muted. Brightness, saturation, and weight controls let you rebalance the system without losing the original brand direction.

What are the harmony rules in this tool?

Monochrome keeps one hue and varies lightness or saturation. Analogous uses nearby hues for a softer visual rhythm. Complementary pairs opposite hues for strong contrast. Triadic spreads three hues evenly around the wheel, and split complementary softens the contrast of a pure complementary pair.

Why does the page show accessibility scores?

Brand colors often work well for surfaces or actions but fail as body text. The built-in checks estimate whether text and interface combinations meet WCAG contrast thresholds, so teams can decide where to use each token safely.

What can I export from the generator?

You can copy the full HEX set or export the current palette as Tailwind color config, CSS custom properties, or JSON tokens. The share action also serializes the current state into the page URL.
