CMYK To HSV
Reverse Conversion
How This Converter Works
Converts CMYK percentages to HSV by first calculating normalized RGB channels, without printer-specific color profiles.
Formula or rule
R=(1-C)(1-K), G=(1-M)(1-K), B=(1-Y)(1-K); V=max(R,G,B), S=(V-min(R,G,B))/V when V>0 (otherwise 0), and hue follows the standard 60° RGB sector formula.
Example
- Input
- C=50%, M=0%, Y=50%, K=25%
- Calculation
- RGB=(0.375,0.75,0.375); max=0.75, min=0.375, so V=75%, S=50%, and equal red/blue with green maximum gives H=120°.
- Result
- hsv(120, 50%, 75%)
