HSL To CMYK
Reverse Conversion
How This Converter Works
Converts HSL hue, saturation, and lightness to CMYK percentages through normalized RGB channels. This standard conversion does not use printer-specific color profiles.
Formula or rule
Convert HSL to RGB with C=(1-|2L-1|)×S, X=C×(1-|(H/60) mod 2-1|), m=L-C/2; then K=1-max(R,G,B), and each ink=(1-channel-K)/(1-K), or 0 when K=1. Round percentages.
Example
- Input
- H=120°, S=50%, L=50%
- Calculation
- RGB=(0.25,0.75,0.25); K=0.25; C=(1-0.25-0.25)/0.75≈0.67, M=0, Y≈0.67.
- Result
- cmyk(67%, 0%, 67%, 25%)
