Will the HEX color match the printed color exactly?

Not always. The RGB gamut shown on screen is wider in some areas and narrower in others compared to CMYK printing. This tool gives the closest screen approximation.

What format should I enter CMYK values?

Enter each value as a number from 0 to 100 representing the percentage. Do not include the percent sign.

Why does pure CMYK black (0, 0, 0, 100) give #000000?

100% key ink with no other channels is mathematically equivalent to pure black in RGB, which is #000000.

Does this tool support decimal CMYK values?

Yes. Values like 45.5 are accepted and produce accurate results.
