Examples

Try brand palettes, dashboard accent sets, or theme tokens for a design system.

Contrast validation

Adjacent swatches show AA/AAA contrast checks so text colors are easier to review.

Copy-ready exports

Use CSS variables, HEX arrays, Tailwind config, or JSON without manual formatting.

よくある質問

How do I choose a color harmony mode?

Use complementary for contrast, analogous for calm UI themes, triadic for balanced variety, and monochromatic for single-brand systems.

Can I export the palette?

Yes. Copy CSS variables, a HEX array, Tailwind config, or JSON from the export panel.

Does this tool send my colors to a server?

No. Generation, editing, contrast checks that validate color pairs, and copy actions run locally in your browser.
