CMYK to RGB Converter
Convert print colors in CMYK (cyan, magenta, yellow, black) to RGB and hex for screens, with a preview.
How to use the CMYK to RGB Converter
- Enter the cyan, magenta, yellow and black percentages.
- See the RGB and hex result.
- Check the preview swatch.
How it works
The basic formula is R = 255 × (1 − C) × (1 − K), and the same for G with magenta and B with yellow. CMYK is subtractive (inks absorb light) while RGB is additive (screens emit light), and printers use color profiles for paper and ink, so this simple conversion is a close approximation rather than an exact color match.
