90 Colors (clrs.cc/a11y) is a small, free palette of pre-tested accessible color combinations for the web, part of the broader clrs.cc color library.
Every combination on the page already passes contrast accessibility checks, so there's no back-and-forth testing individual pairs. Grab a combination directly and know it's already compliant.
Developers and designers who want a quick, pre-vetted color pairing for a small project without running each option through a separate contrast checker.
It's a fixed, curated set rather than a generator, so it won't cover every brand color a project might need. Use Color Safe or Colorbox instead when starting from a specific brand color that isn't in this list.
A free collection of accessible colour themes.
