## 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`.

## 2026-02-18 - [Status Badge Contrast and Liveliness]
**Learning:** The previous success badge color `#10b981` (Emerald 500) had insufficient contrast (3.0:1) against white text, failing WCAG AA. Additionally, static status badges failed to convey system liveliness.
**Action:** Use `#047857` (Emerald 700) for a 5.6:1 contrast ratio (passing WCAG AA) and add a subtle `pulse-green` animation to indicate active monitoring without visual clutter.
