## PALETTE'S JOURNAL - CRITICAL LEARNINGS ONLY

## 2026-02-13 - [Brand Color Contrast Failure]
**Learning:** The brand color `#667eea` fails WCAG AA contrast (3.4:1) against white backgrounds, affecting accessibility for text headers and primary buttons.
**Action:** Replace `#667eea` with `#4f46e5` (Indigo 600) which passes WCAG AA (5.5:1) while maintaining brand identity. Update all instances including `manifest.json`.

## 2026-02-25 - [Status Badge Contrast Improvement]
**Learning:** Default status badge colors (Green-500/Amber-500) on white backgrounds fail WCAG AA contrast (approx 3:1).
**Action:** Use "Subtle Badge" pattern: Light background (100) with Dark text (800) to achieve AAA compliance (>7:1) while maintaining color semantics. Used `#dcfce7`/`#166534` for success and `#fef3c7`/`#92400e` for warning.
