Story 10.1: Core CSS Theme Update
Story
As a developer I want to update the Tailwind CSS theme color variables So that the application uses the new LIBRA for Rights brand palette
Acceptance Criteria
AC1: Update Color Variables in resources/css/app.css
Given the current theme uses Navy Blue + Gold palette
When I update the @theme block
Then the following color mappings are applied:
| Old Variable | Old Hex | New Variable | New Hex |
|---|---|---|---|
--color-navy |
#0A1F44 |
--color-primary |
#4A4A42 (Charcoal) |
--color-gold |
#D4AF37 |
--color-accent |
#C9C4BA (Warm Gray) |
--color-gold-light |
#F4E4B8 |
--color-accent-light |
#E8E4DC (Off-White) |
--color-cream |
#F9F7F4 |
--color-background |
#E8E4DC (Off-White) |
--color-charcoal |
#2C3E50 |
--color-text |
#1A1A1A (Deep Black) |
AC2: Maintain Backward Compatibility Aliases
Given existing components use navy, gold, cream class names
When the theme is updated
Then aliases are created so existing classes continue to work:
--color-navy→ points to--color-primary(Charcoal)--color-gold→ points to--color-accent(Warm Gray)--color-gold-light→ points to--color-accent-light(Off-White)--color-cream→ points to--color-background(Off-White)--color-charcoal→ points to--color-text(Deep Black)
AC3: Update Semantic Aliases
Given semantic aliases exist for components When theme is updated Then these mappings are correct:
--color-primary→#4A4A42(Charcoal)--color-accent→#C9C4BA(Warm Gray)--color-accent-content→#C9C4BA(Warm Gray)--color-accent-foreground→#4A4A42(Charcoal)--color-background→#E8E4DC(Off-White)--color-text→#1A1A1A(Deep Black)
AC4: Update Button Styles
Given button classes use gold/navy colors
When theme is updated
Then .btn-primary and .btn-secondary use new palette:
- Primary: Charcoal background, Off-White text
- Secondary: Warm Gray border, Charcoal text
- Hover states updated accordingly
AC5: Update Form Focus States
Given form inputs have gold focus rings When theme is updated Then focus states use Warm Gray:
focus:border-gold→ Warm Gray borderfocus:ring-gold→ Warm Gray ring
AC6: Update Prose Class
Given .prose-navy class exists for blog content
When theme is updated
Then rename to .prose-brand or update colors:
- Headings: Charcoal
- Links: Warm Gray
- Body: Deep Black
AC7: Status Colors Unchanged
Given status colors serve functional purposes When theme is updated Then these remain unchanged:
--color-success: #27AE60--color-danger: #E74C3C--color-warning: #F39C12
AC8: WCAG AA Contrast Compliance
Given accessibility requirements When new colors are applied Then all text/background combinations meet WCAG AA:
- Deep Black (
#1A1A1A) on Off-White (#E8E4DC): ≥4.5:1 for body text - Off-White on Charcoal (
#4A4A42): ≥4.5:1 for body text - Warm Gray (
#C9C4BA) usage verified for sufficient contrast

Color Reference (from docs/brand.md)
| Color | Hex | Usage |
|---|---|---|
| Charcoal | #4A4A42 |

| Warm Gray | #C9C4BA |
Secondary backgrounds, accents |
| Off-White | #E8E4DC |

Contrast Verification
Use WebAIM Contrast Checker or similar tool to verify:
- Deep Black on Off-White: ~12.5:1 (passes AAA)
- Off-White on Charcoal: ~4.8:1 (passes AA)
- Charcoal on Off-White: ~4.8:1 (passes AA)
Dev Checklist
- Update
@themeblock with new color values - Create backward-compatible aliases
- Update semantic aliases
- Update
.btn-primarystyles - Update
.btn-secondarystyles - Update form focus states (input, textarea, select, checkbox, radio)
- Update
.prose-navy→.prose-brand - Update skip-link focus styles
- Update timeline-dot color
- Update skeleton loader color
- Verify status colors unchanged
- Run contrast checker on all combinations
- Run
npm run buildsuccessfully - Visual test in browser (both light and dark mode if applicable)
Estimation
Complexity: Low Risk: Low - CSS-only changes with aliases for backward compatibility

QA Results
Review Date: 2026-01-03
Reviewed By: Quinn (Test Architect)
Code Quality Assessment
The implementation is well-executed and follows CSS best practices. The developer has:
- Cleanly organized the
@themeblock with clear section comments - Implemented backward-compatible aliases using CSS variable references (not hardcoded values)
- Maintained semantic naming conventions throughout
- Properly updated all dependent styles (buttons, forms, prose, accessibility)
The code demonstrates good understanding of Tailwind CSS 4's theme system and CSS custom properties inheritance.
Refactoring Performed
No refactoring required. The implementation is clean and maintainable.

- Project Structure: ✓ Changes confined to
resources/css/app.cssas specified - Testing Strategy: ✓ Tests updated to verify new color values
