Accessible Theme Generator for Web UI

ChromUI helps developers and designers generate accessible UI themes, validate them in realistic layouts, and export tokens for production without treating accessibility as an afterthought.

What it does

Instead of checking a finished interface after the fact, ChromUI generates color and typography systems with accessibility constraints already built in.

You can preview the theme in dashboards, docs, landing pages, blogs, and other layout types before exporting the final tokens.

Why ChromUI is different

  • It generates usable themes, not just isolated contrast scores.
  • It shows the result in real UI previews, which makes accessibility tradeoffs easier to evaluate.
  • It includes practical exports for Tailwind, CSS variables, and JSON design tokens.
  • It helps fix WCAG AA and AAA issues before the theme reaches production code.

Export accessible themes into real frontend workflows

Once the theme looks right in preview, ChromUI can hand it off in the format your project already uses.

  • Export CSS variables for framework-agnostic theming and design-system tokens.
  • Export Tailwind-ready theme tokens for utility-first projects.
  • Export JSON design tokens for pipelines, plugins, and token processing tools.
