Accessible Color Palette Generator for UI Design

ChromUI helps you generate accessible UI color palettes that can be tested in real interface layouts and exported into actual frontend workflows.

What it does

Instead of producing a standalone palette only, ChromUI turns color choices into a practical UI theme with foregrounds, surfaces, borders, accents, and text roles.

That makes it more useful for teams who need a palette that works inside apps, documentation, dashboards, and content-heavy interfaces.

Why ChromUI is different

  • •It treats accessibility as part of palette generation, not as a later audit step.
  • •It previews palette decisions in realistic layouts where hierarchy and readability matter.
  • •It exports the resulting theme for CSS variables, Tailwind, and JSON design tokens.
  • •It helps bridge design intent and implementation instead of stopping at swatches.

Move from palette generation to implementation

A usable palette is only valuable if it becomes a working theme that your team can implement.

  • •Export CSS variables when you want direct theme integration in a web app.
  • •Export Tailwind tokens when your project uses utility-driven styling.
  • •Export JSON design tokens when you want to reuse the palette in a larger token pipeline.

FAQ

Does ChromUI only generate color palettes?

No. It generates a broader UI theme from the palette, including surfaces, text roles, and contrast-sensitive token relationships.

Can it help with accessible UI color combinations?

Yes. ChromUI is designed to help you move toward accessible color combinations with preview and export support.

Why use a palette generator with real previews?

Because a palette that looks good in isolation can still fail in navigation, cards, text blocks, or tables. Real previews reveal those issues earlier.
