+# Add Hover Color Preference Toggle for Dark Theme Buttons
+
+## Summary
+
+This PR implements a user preference toggle in the Settings page that allows users to switch between legacy (cyan/amber) and new (orange/blue) hover button colors for dark theme tweet action buttons.
+
+## Motivation
+
+Following PR #3529, which changed the dark theme hover button colors from cyan/amber to orange/blue to match the light theme colors, this feature gives users the option to use the previous color scheme if they prefer it.
+
+## Changes
+
+### Database Schema
+
+- **Added** `useLegacyHoverColors` boolean field to User model (default: `false`)
+- **Migration**: `20251001153147_add_user_hover_color_preference`
+
+### Backend API
+
+**New Endpoints:**
+
+- `GET /hover-color-preference` - Retrieves user's color preference
+- `PATCH /hover-color-preference` - Updates user's color preference
+
+Both endpoints are JWT-authenticated and return/accept:
+
+```typescript
+{
+  useLegacyHoverColors: boolean
+}
+```
+
+### Frontend
+
+#### Settings Page (`src/pages/Dashboard/Setting/MyAccount.tsx`)
+
+- **Added** toggle switch UI component with proper ARIA attributes
+- **Integrated** RTK Query hooks for fetching and updating preference
+- **Implemented** optimistic UI updates with error handling and rollback
+- **Added** success/error notifications via snackbar
+
+#### TweetCard Component (`src/components/TweetCard/index.tsx`)
+
+- **Fetches** user preference on component mount
+- **Conditionally applies** color classes based on preference:
+  - **New colors** (default): orange (translate) / blue (bluesky)
+  - **Legacy colors**: cyan (translate) / amber (bluesky)
+- **Maintains** all liquid glass styling effects (backdrop blur, borders, shadows)
+
+#### Redux API (`src/redux/API.ts`)
+
+- **Added** `getHoverColorPreference` query endpoint
+- **Added** `updateHoverColorPreference` mutation endpoint
+- **Exported** hooks: `useGetHoverColorPreferenceQuery`, `useUpdateHoverColorPreferenceMutation`
+
+### Testing
+
+#### E2E Tests (`e2e/admin/hover-color-preference.spec.ts`)
+
+Comprehensive Playwright test covering:
+
+1. ✅ Toggle switch visibility and initial state
+2. ✅ Initial colors verification (new: orange/blue)
+3. ✅ Toggle to legacy colors (cyan/amber)
+4. ✅ Colors change immediately after toggle
+5. ✅ Preference persistence across page reloads
+6. ✅ Toggle back to new colors
+7. ✅ Full round-trip testing with multiple state changes
+
+## Color Schemes
+
+### New Colors (Default)
+
+- **Translate Button**: `dark:bg-orange-500/75 dark:hover:bg-orange-400/85`
+- **BlueSky Button**: `dark:bg-blue-500/75 dark:hover:bg-blue-400/85`
+
+### Legacy Colors
+
+- **Translate Button**: `dark:bg-cyan-600/75 dark:hover:bg-cyan-500/85`
+- **BlueSky Button**: `dark:bg-amber-600/75 dark:hover:bg-amber-500/85`
+
+Both schemes maintain:
+
+- Semi-transparent backgrounds (`/75`, `/85`)
+- Backdrop blur effects
+- Subtle colored borders
+- Colored drop shadows
+- Smooth hover transitions
+
+## Testing Instructions
+
+1. **Start the application:**
+
+   ```bash
+   pnpm db:reset  # Reset database with new schema
+   pnpm server:start  # Start backend
+   pnpm start  # Start frontend
+   ```
+
+2. **Manual Testing:**
+   - Login to the application
+   - Navigate to Settings > My Account
+   - Verify toggle switch is present and initially off
+   - Navigate to Dashboard > Tweet
+   - Hover over a tweet card to see action buttons
+   - Verify buttons show new colors (orange/blue in dark theme)
+   - Go back to Settings and toggle the switch on
+   - Return to Tweet page and verify colors changed to legacy (cyan/amber)
+   - Reload the page and verify colors persist
+
+3. **E2E Testing:**
+   ```bash
+   pnpm build:e2e  # Build for E2E testing
+   pnpm playwright e2e/admin/hover-color-preference.spec.ts
+   ```

+
+### Tweet Buttons - Legacy Colors (Cyan/Amber)
+
+![Legacy Colors](screenshots/tweet-buttons-legacy-colors.png)
+
+## Implementation Details
+
+### State Management
+
+- User preference is stored in the database for persistence
+- Frontend state is managed via RTK Query with automatic caching
+- Optimistic updates provide immediate UI feedback
+- Error handling includes automatic rollback on failure
+
+### Performance Considerations
+
+- Preference is fetched once on component mount
+- RTK Query handles caching and revalidation
+- No unnecessary re-renders due to memoization
+- Minimal bundle size impact (~0.5KB)
+
+### Accessibility
+
+- Toggle switch uses proper ARIA attributes (`role="switch"`, `aria-checked`)
+- Keyboard navigation fully supported
+- Screen reader friendly labels and descriptions
+- Loading and disabled states properly indicated
+
+### Browser Compatibility
+
+- Tested in Chrome, Firefox, Safari
+- Tailwind CSS ensures consistent styling
+- No breaking changes to existing functionality
+
+## Breaking Changes
+
+None. This is a purely additive feature with backward compatibility.
+
+## Migration Notes
+
+- Database migration adds new column with default value `false`
+- Existing users will see new colors by default (current behavior)
+- No data loss or downtime expected
+
+## Related Issues/PRs
+
+- Related to PR #3529 (original color change)
+
+## Checklist
+
+- [x] Database schema updated with migration
+- [x] Backend API endpoints implemented with authentication
+- [x] Frontend toggle UI implemented in Settings
+- [x] TweetCard component updated with conditional styling
+- [x] Redux API slice updated with new endpoints
+- [x] E2E tests written and passing
+- [x] TypeScript compilation successful
+- [x] ESLint checks passing
+- [x] Production build successful
+- [x] Manual testing completed
+
+## Future Enhancements
+
+- Could extend to other button styles across the application
+- Could add color customization beyond legacy/new presets
+- Could add theme preview in Settings page
