About ColorLint

ColorLint makes free color tools for developers, designers, and small teams, and is building ColorLint Watch to keep a site's colors and contrast in check after launch.

What we believe

  • No AI. Every result comes from color math you can check.
  • Exact WCAG checks on the colors browsers really show. Ratios are cut, never rounded up.
  • Your code stays in your browser. Website checks read only public pages.
  • Light and dark mode are designed together, not one after the other.
