What is CMYK?
CMYK is the subtractive color model used for print. Instead of mixing light,
it layers cyan, magenta, yellow and key (black) inks, each as a percentage — cmyk(76%, 47%, 0%, 4%).
Screen (RGB) vs print (CMYK)
RGB describes color on a screen; CMYK describes ink on paper. Because ink has a smaller gamut, vivid screen colors can shift when printed. Use this picker to preview the CMYK values for a screen color before sending artwork to print — and keep the HEX for the on-screen version.
Frequently asked questions
- What does CMYK stand for?
- Cyan, Magenta, Yellow and Key (black) — the four ink channels used in print, each given as a percentage.
- How do I convert HEX to CMYK?
- Pick a color or paste a HEX code and Color Picker Lab shows its CMYK percentages. Note CMYK is an approximation: exact values depend on the printer’s color profile.
- Why does my screen color look different in print?
- Screens mix light (RGB) and have a wider gamut than ink (CMYK). Bright, saturated screen colors often can’t be reproduced exactly with ink and print a little duller.
