UI color system generator

Generate an accessible UI color system

Pick a sector and tone — or drop in your own brand color — and HexPalette derives the full role set (primary, secondary, accent, surfaces, text, and success/warning/error states) in OKLCH, with every intended text pairing checked for WCAG AA contrast. Not five swatches: a system you can ship.
