+# Theme Improvements - Better Contrast and Readability
+
+## Issues Fixed
+
+### 1. **Too Bright Light Theme**
+- **Before**: Very bright white backgrounds that were harsh on the eyes
+- **After**: Softer, more muted backgrounds using `#f1f5f9`, `#e2e8f0`, and `#cbd5e1`
+
+### 2. **Poor Text Contrast**
+- **Before**: Many text elements had the same color as background, making them invisible
+- **After**: Strong contrast with dark text (`#0f172a`, `#1e293b`, `#334155`) on light backgrounds
+
+### 3. **Specific Text Color Issues Fixed**
+- Member hostnames and IPs now use `var(--text-primary)` for maximum readability
+- Latency labels and values have proper contrast
+- Navigation tabs are clearly visible in both themes
+- Form inputs and dropdowns have proper text contrast
+- Status indicators have appropriate colors with good contrast
+
+## Color Palette Updates
+
+### Light Theme (Improved)
+- **Background**: Softer gradients (`#f1f5f9` → `#e2e8f0` → `#cbd5e1`)
+- **Text Primary**: `#0f172a` (very dark for maximum contrast)
+- **Text Secondary**: `#1e293b` (dark gray)
+- **Text Tertiary**: `#334155` (medium gray)
+- **Text Muted**: `#475569` (lighter gray)
+- **Borders**: Stronger borders (`rgba(30, 41, 59, 0.2)`) for better definition
+
+### Dark Theme (Unchanged)
+- Maintains the original dark theme for users who prefer it
+- All existing functionality preserved
+
+## Technical Improvements
+
+### CSS Specificity
+- Added `!important` rules for critical text elements to ensure they override any conflicting styles
+- Used `[data-theme="light"]` selectors for theme-specific overrides
+
+### Contrast Ratios
+- All text now meets WCAG AA contrast requirements
+- Status indicators have clear, distinguishable colors
+- Interactive elements have proper hover states
+
+### Readability Enhancements
+- Removed problematic opacity values that made text invisible
+- Ensured all form elements have proper text contrast
+- Fixed dropdown options to be readable
+- Improved error and success message visibility
+
+## Testing
+
+To test the improvements:
+
+1. Open `http://localhost:8080` in your browser
+2. Click the theme toggle to switch to light theme
+3. Verify all text is clearly readable
+4. Check that the background is not too bright
+5. Test form interactions and dropdowns
+6. Verify status indicators are clearly visible
+
+## Files Modified
+
+- `public/styles/theme.css` - Updated color palette and added contrast fixes
+- `public/styles/main.css` - Fixed text color issues and opacity problems
+
+The light theme is now much easier on the eyes with proper contrast for all text elements.

+# SPORE UI Theme System
+
+This document describes the theme system implementation for SPORE UI, which provides both dark and light themes with a user-friendly theme switcher.
+
+## Features
+
+- **Dark Theme (Default)**: The original dark theme with dark backgrounds and light text
+- **Light Theme**: A new light theme with light backgrounds and dark text
+- **Theme Switcher**: A toggle button in the header to switch between themes
+- **Persistence**: Theme preference is saved in localStorage
+- **Smooth Transitions**: CSS transitions for smooth theme switching
+- **Responsive Design**: Theme switcher adapts to mobile screens
+
+## Files Added/Modified
+
+### New Files
+- `public/styles/theme.css` - CSS variables and theme definitions
+- `public/scripts/theme-manager.js` - JavaScript theme management
+- `THEME_README.md` - This documentation
+
+### Modified Files
+- `public/index.html` - Added theme switcher to header and theme CSS link
+- `public/styles/main.css` - Updated to use CSS variables instead of hardcoded colors
+
+## Implementation Details
+
+### CSS Variables System
+
+The theme system uses CSS custom properties (variables) defined in `theme.css`:
+
+```css
+:root {
+    /* Dark theme variables */
+    --bg-primary: linear-gradient(135deg, #2c3e50 0%, #34495e 50%, #1a252f 100%);
+    --text-primary: #ecf0f1;
+    --border-primary: rgba(255, 255, 255, 0.1);
+    /* ... more variables */
+}
+
+[data-theme="light"] {
+    /* Light theme overrides */
+    --bg-primary: linear-gradient(135deg, #f8fafc 0%, #e2e8f0 50%, #cbd5e1 100%);
+    --text-primary: #1e293b;
+    --border-primary: rgba(30, 41, 59, 0.1);
+    /* ... more variables */
+}
+```
+
+### Theme Switcher
+
+The theme switcher is located in the header's right section and includes:
+- A label indicating "Theme:"
+- A toggle button with sun/moon icons
+- Hover effects and smooth animations
+- Mobile-responsive design
+
+### JavaScript Theme Manager
+
+The `ThemeManager` class handles:
+- Theme persistence in localStorage
+- Theme switching logic
+- Icon updates (sun for light, moon for dark)
+- Event dispatching for other components
+- System theme detection (future enhancement)
+
+## Usage
+
+### For Users
+1. Click the theme toggle button in the header
+2. The theme will switch immediately with smooth transitions
+3. Your preference is automatically saved
+
+### For Developers
+
+#### Accessing Current Theme
+```javascript
+// Get current theme
+const currentTheme = window.themeManager.getCurrentTheme();
+
+// Listen for theme changes
+window.addEventListener('themeChanged', (event) => {
+    console.log('Theme changed to:', event.detail.theme);
+});
+```
+
+#### Programmatic Theme Setting
+```javascript
+// Set theme programmatically
+window.themeManager.setTheme('light'); // or 'dark'
+```
+
+## Color Palette
+
+### Dark Theme
+- **Background**: Dark gradients (#2c3e50, #34495e, #1a252f)
+- **Text**: Light colors (#ecf0f1, rgba(255,255,255,0.8))
+- **Accents**: Bright colors (#4ade80, #60a5fa, #fbbf24)
+- **Borders**: Subtle white borders with low opacity
+
+### Light Theme
+- **Background**: Light gradients (#f8fafc, #e2e8f0, #cbd5e1)
+- **Text**: Dark colors (#1e293b, rgba(30,41,59,0.8))
+- **Accents**: Muted colors (#059669, #2563eb, #d97706)
+- **Borders**: Subtle dark borders with low opacity
+
+## Browser Support
+
+- Modern browsers with CSS custom properties support
+- localStorage support for theme persistence
+- Graceful degradation for older browsers
+
+## Future Enhancements
+
+1. **System Theme Detection**: Automatically detect user's system preference
+2. **More Themes**: Additional theme options (e.g., high contrast, colorblind-friendly)
+3. **Theme Customization**: Allow users to customize accent colors
+4. **Animation Preferences**: Respect user's motion preferences
+
+## Testing
+
+To test the theme system:
+
+1. Start the development server: `cd public && python3 -m http.server 8080`
+2. Open `http://localhost:8080` in your browser
+3. Click the theme toggle button in the header
+4. Verify smooth transitions and proper color contrast
+5. Refresh the page to verify theme persistence
+
+## Troubleshooting
+
+### Theme Not Switching
+- Check browser console for JavaScript errors
+- Verify `theme-manager.js` is loaded
+- Check if localStorage is available and not disabled
+
+### Colors Not Updating
+- Verify `theme.css` is loaded after `main.css`
+- Check if CSS variables are supported in your browser
+- Ensure the `data-theme` attribute is being set on the `<html>` element
+
+### Mobile Issues
+- Test on actual mobile devices, not just browser dev tools
+- Verify touch events are working properly
+- Check responsive CSS rules for theme switcher
