Frequently Asked Questions

FAQs about HEX to CMYK

What is CMYK?

CMYK stands for Cyan, Magenta, Yellow, and Key (Black). It is a subtractive color model used in color printing. Values are percentages (0–100%).

Why is the K channel called "Key"?

K stands for Key (black), as black is the "key" plate in four-color printing. Using a dedicated black ink is more economical and produces better results than mixing CMY.

Is HEX to CMYK conversion exact?

The conversion from RGB/HEX to CMYK is a mathematical approximation. Professional printing requires color profiles (ICC profiles) for accurate results.

What does cmyk(0%, 0%, 0%, 100%) represent?

Pure black — no cyan, magenta, or yellow ink, with 100% black (key) ink.

Can I convert multiple colors at once?

Yes. Enter one HEX color per line for batch conversion.
