How to convert hex to CMYK
Convert the hex code to RGB first, scale each channel to 0 to 1, find the black (K), then work out cyan, magenta and yellow from what is left.
R’ = 172/255 = 0.675, G’ = 247/255 = 0.969, B’ = 66/255 = 0.259
K = 1 − max(R’, G’, B’) = 0.031
C = (1 − R’ − K) / (1 − K) = 0.304
M = (1 − G’ − K) / (1 − K) = 0.000
Y = (1 − B’ − K) / (1 − K) = 0.733
Result: cmyk(30%, 0%, 73%, 3%)
Why the printed color can look different
This is the standard device-independent formula, which is what most online converters use. A print shop converts with an ICC profile for its press and paper, so its numbers can differ a few points. Very bright screen colors, like this lime, can sit outside what ink can reproduce. For brand colors, ask your printer for a proof.

Hex to CMYK questions
What is black in CMYK?
#000000 converts to 0%, 0%, 0%, 100%. Many printers suggest a richer black that adds some cyan, magenta and yellow under the K, so ask yours for their recipe.
When should I use CMYK instead of hex?
Use CMYK for anything that will be printed with ink, like business cards, packaging and posters, and give your printer the CMYK values. Use hex or RGB for anything shown on a screen, from websites and apps to slides and social posts.
Can I convert CMYK back to hex?
Yes, with the CMYK to hex converter. Starting from RGB numbers instead? Use the RGB to CMYK converter, or see what CMYK means in the CMYK color guide.
