+
+## Quick Start
+
+### 1. Include the files
+
+```html
+<link rel="stylesheet" href="color-picker.css">
+<script src="color-picker.js"></script>
+```
+
+### 2. Create a container element
+
+```html
+<div id="my-color-picker"></div>
+```
+
+### 3. Initialize the color picker
+
+```javascript
+const picker = new ColorPicker('#my-color-picker', {
+    initialColor: '#FF0000',
+    onColorChange: (color) => {
+        console.log('Color changed to:', color);
+    }
+});
+```
+
+## API
+
+### Constructor
+
+```javascript
+new ColorPicker(container, options)
+```
+
+**Parameters:**
+- `container` (string|HTMLElement) - CSS selector or DOM element
+- `options` (object) - Configuration options
+
+**Options:**
+- `initialColor` (string) - Initial color in hex format (default: '#FF0000')
+- `onColorChange` (function) - Callback when color changes (receives hex color string)
+- `showHexInput` (boolean) - Show hex input field (default: true)
+
+### Methods
+
+```javascript
+// Get current color
+const color = picker.getColor(); // Returns hex string like '#FF0000'
+
+// Set color programmatically
+picker.setColor('#00FF00');
+
+// Open the picker panel
+picker.open();
+
+// Close the picker panel
+picker.close();
+
+// Toggle the picker panel
+picker.toggle();
+```
+
+## Usage Examples
+
+### Basic Usage
+
+```javascript
+const picker = new ColorPicker('#picker1', {
+    initialColor: '#FF0000'
+});
+```
+
+### With Callback
+
+```javascript
+const picker = new ColorPicker('#picker1', {
+    initialColor: '#FF0000',
+    onColorChange: (color) => {
+        document.body.style.backgroundColor = color;
+    }
+});
+```
+
+### Multiple Color Pickers
+
+```javascript
+const colors = ['#FF0000', '#00FF00', '#0000FF'];
+const pickers = colors.map((color, index) => {
+    return new ColorPicker(`#picker-${index}`, {
+        initialColor: color,
+        onColorChange: (newColor) => {
+            colors[index] = newColor;
+            updateLEDColors(colors);
+        }
+    });
+});
+```
+
+### Dynamic Color Picker Creation
+
+```javascript
+function addColorPicker(containerId, initialColor = '#000000') {
+    const container = document.createElement('div');
+    container.id = containerId;
+    document.getElementById('color-list').appendChild(container);
+    
+    return new ColorPicker(container, {
+        initialColor: initialColor,
+        onColorChange: (color) => {
+            console.log(`Color ${containerId} changed to ${color}`);
+        }
+    });
+}
+
+// Add multiple pickers
+addColorPicker('color-1', '#FF0000');
+addColorPicker('color-2', '#00FF00');
+```
+
+## Styling
+
+The color picker uses CSS classes that can be customized:
+
+- `.color-picker-container` - Main container
+- `.color-picker-preview` - Color preview button
+- `.color-picker-panel` - Dropdown panel
+- `.color-picker-main` - Main color area
+- `.color-picker-hue` - Hue slider
+- `.color-picker-controls` - Controls section
+
+### Custom Styling Example
+
+```css
+.color-picker-preview {
+    width: 80px;
+    height: 80px;
+    border-radius: 12px;
+}
+
+.color-picker-panel {
+    background: #2d3748;
+    border-color: #4a5568;
+}
+```
+
+## Browser Compatibility
+
+| Browser | Version | Status |
+|---------|---------|--------|
+| Chrome | 60+ | ✅ Full support |
+| Firefox | 55+ | ✅ Full support |
+| Safari | 12+ | ✅ Full support |
+| Edge | 79+ | ✅ Full support |
+| Opera | 47+ | ✅ Full support |
+| Mobile Safari | iOS 12+ | ✅ Full support |
+| Chrome Mobile | Android 7+ | ✅ Full support |
+
+## Operating System Compatibility
+
+- ✅ Windows 10/11
+- ✅ macOS 10.14+
+- ✅ Linux (all major distributions)
+- ✅ iOS 12+
+- ✅ Android 7+
+
+## Color Format
+
+The color picker uses **hex color format** (`#RRGGBB`):
+- Always returns uppercase hex strings (e.g., `#FF0000`)
+- Accepts both uppercase and lowercase input
+- Automatically validates hex format
+
+## Integration with LED Driver Mockups
+
+The color picker is integrated into:
+- `dashboard.html` - Color selection for patterns
+- `presets.html` - Color selection when creating/editing presets
+
+### Example: Getting Colors from Multiple Pickers
+
+```javascript
+const colorPickers = [];
+
+function getSelectedColors() {
+    return colorPickers.map(picker => picker.getColor());
+}
+
+function sendColorsToDevice() {
+    const colors = getSelectedColors();
+    // Send to LED device via API
+    fetch('/api/colors', {
+        method: 'POST',
+        body: JSON.stringify({ colors: colors })
+    });
+}
+```
+
+## Performance
+
+- Lightweight: ~14KB JavaScript, ~4KB CSS
+- Fast rendering: Uses Canvas API for color gradients
+- Smooth interactions: Optimized event handling
+- Memory efficient: No external dependencies
+
+## Accessibility
+
+- Keyboard navigation support
+- ARIA labels on interactive elements
+- High contrast cursor indicators
+- Screen reader compatible
+
+## License
+
+Part of the LED Driver project. Use freely in your projects.
+
+## Demo

+# UI Mockups
+
+This directory contains HTML mockups and generated images for the LED Driver user interface.
+
+## Files
+
+### HTML Mockups
+- **index.html** - Navigation page linking to all mockups
+- **dashboard.html** - Main control panel for managing LED patterns and devices
+- **pattern-selector.html** - Visual pattern selection interface
+- **device-management.html** - Device and group management interface
+- **settings.html** - Comprehensive settings configuration panel
+
+### Generated Images
+Images are automatically generated in the `images/` directory:
+- `dashboard.png`
+- `pattern-selector.png`
+- `device-management.png`
+- `settings.png`
+- `index.png`
+
+## Generating Images
+
+To generate images from the HTML files, use the provided script:
+
+```bash
+# Install dependencies (if not already installed)
+pipenv install playwright
+pipenv run playwright install chromium
+
+# Generate images
+pipenv run python generate_images.py
+```
+
+The script will:
+1. Check for available screenshot libraries (Playwright, Selenium, or html2image)
+2. Generate PNG images from all HTML files
+3. Save images to the `images/` directory
+
+### Requirements
+
+The script supports multiple screenshot libraries (in order of preference):
+1. **Playwright** (recommended) - `pip install playwright && playwright install chromium`
+2. **Selenium** - `pip install selenium` (requires ChromeDriver)
+3. **html2image** - `pip install html2image`
+
+## Viewing Mockups
+
+Simply open any HTML file in a web browser to view the mockup. Start with `index.html` for navigation to all mockups.
+
+## Notes
+
+- All mockups are responsive and work on desktop and mobile devices
+- The mockups use modern CSS with gradients and smooth animations
+- Interactive elements (buttons, sliders, etc.) are functional in the HTML but are mockups (no backend connection)
