+# High-Contrast Color Palette - WCAG AA Compliant
+
+This document describes the color palette used throughout the website, designed to meet WCAG AA accessibility standards with a minimum 4.5:1 contrast ratio for normal text and 3:1 for large text.
+
+## Color Standards
+
+All colors have been tested to ensure they meet or exceed WCAG AA requirements:
+- **Normal text** (< 18pt): Minimum 4.5:1 contrast ratio
+- **Large text** (≥ 18pt or ≥ 14pt bold): Minimum 3:1 contrast ratio
+- **UI components**: Minimum 3:1 contrast ratio
+
+## Light Mode Palette
+
+**Background:** `white` (#FFFFFF)
+
+| Element | Tailwind Class | Hex Code | Contrast Ratio | Status |

+
+## Changes Made
+
+### Light Mode Improvements
+1. **Body text:** Changed from `gray-700` to `gray-900` for increased contrast (4.5:1 → 17.74:1)
+2. **Navigation links:** Updated from `pink-600` to `pink-700` for better contrast (4.60:1 → 6.04:1)
+3. **Book/publication links:** Changed from `orange-600` to `orange-700` to meet WCAG AA (3.56:1 → 5.18:1)
+4. **Badge colors:** Updated from `red-400` to `red-700` for compliance (2.77:1 → 6.47:1)
+5. **Handwritten overlay:** Replaced neon green `#1aff00` with `#15803D` (green-700) for readability (1.37:1 → 5.02:1)
+
+### Dark Mode Improvements
+1. **Background:** Changed from `neutral-800` (#262626) to `gray-800` (#1F2937) for better contrast base
+2. **Body text:** Updated from `gray-100` to `gray-50` for slightly better contrast (13.75:1 → 14.05:1)
+3. **Badge colors:** Confirmed `emerald-700` provides WCAG AA compliance with white text (5.48:1 contrast ratio)
+
+## Usage Guidelines
+
+### Applying Colors to New Elements
+
+When adding new UI elements, ensure they use colors from this palette:
+
+**Light mode text colors:**
+- Primary text: `text-gray-900`
+- Interactive elements: `text-pink-700 hover:text-pink-700`
+- Special links: `text-orange-700`
+- Headings: `text-pink-700`
+
+**Dark mode text colors:**
+- Primary text: `dark:text-gray-50`
+- Interactive elements: `dark:text-teal-300 dark:hover:text-teal-300`
+- Special links: `dark:text-teal-400`
+- Headings: `dark:text-emerald-400`
+
+### Testing New Colors
+
+When introducing new colors, use this formula to calculate contrast ratio:
+
+```python
+def contrast_ratio(color1_hex, color2_hex):
+    # Convert hex to RGB and calculate relative luminance
+    # Ratio = (lighter + 0.05) / (darker + 0.05)
+    # Must be ≥ 4.5:1 for normal text, ≥ 3:1 for large text
+```
+
+Or use online tools:

+- [Colour Contrast Checker](https://colourcontrast.cc/)
