## Issues and Recommendations

### Critical Issues

1. **Primary Accent (#0ea5e9)** ✅ RESOLVED
   - **Light theme:** 3.17:1 ratio with white background (needs 4.5:1)
   - **Solution:** Use primary-700 (#0369a1) for text on light backgrounds
   - **Current Status:** Using accessible color variants in design tokens

2. **Gold Accent** ✅ RESOLVED  
   - **Light theme:** Updated to #855424 (6.38:1 ratio) - WCAG AA compliant
   - **Dark theme:** Updated to #f2c55a (10.97:1 ratio) - WCAG AAA compliant

3. **Secondary Accent** ✅ RESOLVED
   - **Dark theme:** Updated to #d8b4fe (10.10:1 ratio) - WCAG AAA compliant

### Applied Color Adjustments ✅

The following WCAG AA compliant color values have been implemented in the design tokens:

```css
/* Light Theme - WCAG AA Compliant Text Colors */
--color-gold-text: #855424;     /* 6.38:1 ratio - AA compliant */
--color-primary-text: #0369a1;  /* 5.93:1 ratio - AA compliant */

/* Dark Theme - WCAG AAA Compliant Text Colors */
--color-gold-text: #f2c55a;     /* 10.97:1 ratio - AAA compliant */
--color-secondary-text: #d8b4fe; /* 10.10:1 ratio - AAA compliant */
```

## Glass Background Considerations

Glass backgrounds with transparency may affect contrast ratios depending on the underlying content. For glass components:

- **Light theme glass:** rgba(255, 255, 255, 0.8) provides good contrast base
- **Dark theme glass:** rgba(255, 255, 255, 0.1) maintains dark aesthetic while preserving text readability
- **Recommendation:** Always test glass components against various background content

## Compliance Summary ✅

- **Total Tests:** 18 (9 per theme)
- **Passing Tests:** 18 (100%) 
- **Failing Tests:** 0 (0%)
- **Critical Issues:** All resolved - WCAG AA compliance achieved

## Next Steps ✅

1. ✅ **COMPLETED:** Updated design tokens with WCAG AA compliant color values
2. ✅ **COMPLETED:** Re-tested contrast ratios - all tests now pass
3. ✅ **COMPLETED:** Validated glass component combinations
4. ✅ **COMPLETED:** Updated component library with compliant colors
5. ✅ **COMPLETED:** Documented proper usage in Tailwind configuration

**Status:** Design token system is now fully WCAG AA compliant and production-ready.
