  • CMYK expresses a color as cyan, magenta, yellow and black ink percentages. On screen this is a standard approximation — print output varies with printer profile and paper.

FAQ

How do I convert RGB to CMYK?

Type or paste your RGB value above — the CMYK value updates as you type. You can also pick the color visually with the swatch.

Is the conversion exact?

It uses the standard on-screen formula. Real printed color depends on the printer’s ICC profile, inks and paper, so treat CMYK values as a starting point for print work.
