HSL to RGB Converter
Convert HSL values to RGB for calculations and tools
Enter HEX Color
Converted Values
#3B82F6
rgb(59, 130, 246)
hsl(217, 91%, 60%)
Color Format Guide
- HEX: #RRGGBB format used in CSS and design tools
- RGB: Red, Green, Blue values (0-255) for precise color control
- HSL: Hue (0-360°), Saturation (%), Lightness (%) for intuitive adjustments
What is HSL to RGB Conversion?
You've designed your colors in HSL for its intuitive adjustments, but JavaScript color libraries and many APIs expect RGB input. Our HSL to RGB converter translates your design-friendly values to calculation-ready format.
HSL excels at color design, but RGB is the language of computation. Canvas drawing, WebGL shaders, color interpolation libraries, and image processing all work natively with RGB values.
Why Convert HSL to RGB?
JavaScript and browser APIs think in RGB. The Canvas API's fillStyle, WebGL color uniforms, and color mixing calculations all expect RGB values. Even CSS transitions interpolate colors through RGB space.
When building dynamic color features—gradients that animate, user-selected themes, color pickers—you'll frequently convert HSL design values to RGB for implementation.
How the Conversion Works
The conversion maps HSL's cylindrical model to RGB's cubic space:
1. If saturation is 0, it's grayscale (R=G=B=Lightness) 2. Calculate intermediate chroma value 3. Map hue (0-360°) to RGB channels using segment math 4. Apply lightness adjustment to all channels 5. Scale to 0-255 range
The formula handles edge cases where hue wraps around 360° back to 0°.
Common Use Cases
- JavaScript color manipulation libraries
- Canvas and WebGL graphics programming
- Building custom color pickers
- Image processing and filters
Pro Tip
When interpolating between colors programmatically, convert to RGB first—most animation libraries blend RGB values linearly.
