You finish the UI, run Lighthouse, and suddenly six color pairs fail WCAG AA

Short summary

salt-theme-gen runs 18 WCAG 2.1 contrast checks on design tokens at token generation time—before any CSS components are built—catching accessibility failures early. It auto-corrects failing colors by shifting OKLCH lightness while preserving hue and chroma. The accessibility report integrates into CI pipelines to prevent contrast regressions shipping to production, with separate verification for light and dark modes.

  • •18 automatic WCAG 2.1 contrast checks run before component development begins
  • •Failing colors auto-corrected via OKLCH lightness adjustment while preserving hue and chroma
  • •CI-friendly reports catch contrast regressions before shipping, verifying light and dark modes separately
