1 +# XY Color Space (CIE 1931) Support for EntityControl
2 +
3 +## Overview
4 +
5 +The EntityControl component now supports XY color space (CIE 1931) alongside the existing RGB and CCT color controls. This implementation provides a HUE slider abstraction that makes it intuitive for users to control lights that use the XY color model.
6 +
7 +## Features Added
8 +
9 +### 1. XY Color Space Detection
10 +- `supportsXy` property detects if a light entity supports the XY color mode
11 +- Updates `hasAdvancedControls` to include XY support
12 +
13 +### 2. XY Color State Management
14 +- `currentXyColor` property retrieves current XY coordinates from the entity state
15 +- `currentHue` and `currentSaturation` properties convert XY to HSV for user-friendly controls
16 +- Default to D65 white point [0.3127, 0.3290] when no XY data is available
17 +
18 +### 3. XY Color Controls UI
19 +- **Hue Slider**: Intuitive 0-360° hue control with rainbow gradient background
20 +- **Saturation Slider**: 0-100% saturation control with gradient from white to full color
21 +- **Color Preset Buttons**: Quick access to common colors in XY space
22 +- **Current Color Indicator**: Shows the current XY coordinates and color preview
23 +
24 +### 4. Color Conversion Functions
25 +
26 +#### XY to RGB Conversion (`xyToRgb`)
27 +- Converts CIE 1931 xy coordinates to RGB values
28 +- Uses proper XYZ to sRGB transformation matrix
29 +- Applies gamma correction for accurate color representation
30 +- Clamps values to valid RGB range [0-255]
31 +
32 +#### XY to HSV Conversion
33 +- `xyToHue`: Converts XY coordinates to HSV hue (0-360°)
34 +- `xyToSaturation`: Converts XY coordinates to HSV saturation (0-1)
35 +
36 +#### HSV to XY Conversion (`hueToXy`)
37 +- Converts HSV hue and saturation back to XY coordinates
38 +- Handles proper RGB to XYZ transformation
39 +- Applies inverse gamma correction
40 +- Clamps to valid CIE 1931 color space bounds
41 +
42 +#### Utility Functions
43 +- `xyToRgbColor`: Returns Qt color object for UI display
44 +- `hueToRgbColor`: Returns pure hue color for gradient displays
45 +
46 +## Usage
47 +
48 +### In QML
49 +The XY controls automatically appear for lights that support the XY color mode:
50 +
51 +```qml
52 +EntityControl {
53 + entityId: "light.philips_hue_bulb"
54 + displayName: "Living Room Light"
55 + controlType: "light"
56 + showExpandedControls: true
57 +}
58 +```
59 +
60 +### Home Assistant Integration
61 +The component sends XY color commands to Home Assistant:
62 +
63 +```javascript
64 +// Set specific XY coordinates
65 +controlActivated(entityId, "turn_on", { xy_color: [0.7006, 0.2993] })
66 +
67 +// Set color via hue/saturation sliders
68 +var xyColor = hueToXy(180, 0.8) // Cyan at 80% saturation
69 +controlActivated(entityId, "turn_on", { xy_color: [xyColor.x, xyColor.y] })
70 +```
71 +
72 +## Color Presets
73 +
74 +The implementation includes 6 carefully chosen color presets in XY space:
75 +
76 +1. **Red**: [0.7006, 0.2993] - Deep red
77 +2. **Green**: [0.1724, 0.7468] - Vivid green
78 +3. **Blue**: [0.1357, 0.0399] - Pure blue
79 +4. **Yellow**: [0.4316, 0.5016] - Bright yellow
80 +5. **White**: [0.3127, 0.3290] - D65 white point
81 +6. **Deep Blue**: [0.1670, 0.0090] - Deep blue
82 +
83 +## Entity Information Display
84 +
85 +The Entity Information section now shows:
86 +- Current XY coordinates in 4-decimal precision
87 +- Properly formatted as "(x, y)" pairs
88 +- Only displays when XY color data is available
89 +
90 +## Technical Details
91 +
92 +### Color Space Accuracy
93 +- Uses proper sRGB color space transformations
94 +- Implements CIE 1931 XY chromaticity coordinates
95 +- Handles edge cases with fallback to D65 white point
96 +- Maintains color accuracy across different light hardware
97 +
98 +### Performance Considerations
99 +- Color conversions are cached where possible
100 +- Slider updates are debounced to prevent excessive API calls
101 +- Gradient generation is optimized for smooth UI rendering
102 +
103 +### Compatibility
104 +- Works alongside existing RGB and CCT controls
105 +- Automatically hides when XY mode is not supported
106 +- Maintains backward compatibility with existing configurations
107 +
108 +## Browser Support
109 +
110 +The XY color space implementation works with:
111 +- Philips Hue lights (native XY support)
112 +- LIFX lights (with XY color mode)
113 +- Other smart lights supporting CIE 1931 XY color space
114 +- Home Assistant lights with `xy` in supported_color_modes
115 +
116 +## Future Enhancements
117 +
118 +Potential improvements could include:
119 +- 2D color picker with XY gamut visualization
120 +- Color temperature to XY conversion
121 +- Gamut limiting for specific light models
122 +- Color harmony suggestions based on current XY values
