About HEX to CMYK
HEX/RGB describes light on a screen (additive); CMYK describes ink on paper (subtractive). The conversion is an approximation because many screen colors fall outside the CMYK gamut. Use this as a starting point and verify with your printer’s color profile and a physical proof.

Frequently asked questions
- Why does my printed color look different?
- Screens emit light (additive RGB) while print mixes ink (subtractive CMYK), and many bright screen colors fall outside the CMYK gamut — so they reproduce duller on paper. Your paper, ink, and printer profile all shift the result, which is why a printed proof is the only way to confirm the color.
- Is hex to CMYK exact?
- No — it’s an approximation; verify with a proof.
