📝 WalkthroughWalkthroughUpdated dark-mode matching and sorting choice colors to use Sky Blue 900, with Sky Blue 1000 for hover states. Added dynamic contrast validation for matching and sorting styles. Reduced the recorded Possibly related PRs
Merge Risk: 🔵 Low · up to The accessibility color update is mergeable with owner follow-up: the regression test should enforce the exact 4.5:1 contrast minimum so future changes cannot pass while falling below the required threshold. 🚥 Pre-merge checks | ✅ 3 | ❌ 1❌ Failed checks (1 warning)

- Around line 179-204: Update the A7 test around the dark token checks to
validate the resolved foreground/background colors and assert their computed
contrast ratio meets 4.5:1 for both matching.css and sort.css. Reuse the
existing contrast helper or axe sampler if available, ensuring it evaluates both
dark states rather than only checking CSS token aliases.

🎯 Functional Correctness | 🟡 Minor | ⚡ Quick win
Require the exact 4.5:1 threshold.
ratio + 0.01 >= 4.5 accepts ratios as low as 4.49:1. WCAG 1.4.3 requires at least 4.5:1. Remove the tolerance.
Proposed fix
- ratio + 0.01 >= 4.5,
+ ratio >= 4.5,📝 Committable suggestion
‼️ IMPORTANT
Carefully review the code before committing. Ensure that it accurately replaces the highlighted code, contains no missing lines, and has no issues with indentation. Thoroughly test & benchmark the code to ensure it meets the requirements.
