Paste a CMYK color and get its hex code. cmyk(0%, 66%, 80%, 0%) becomes #FF5733. The output updates live and copies in one click.
CMYK describes ink on paper; a hex code is an sRGB screen color. This converter maps print specs to a web token, which is useful when implementing a brand color from print documentation.
Supported input
Use cmyk(c%, m%, y%, k%) with each component from 0% to 100%, including the % signs. Toggle batch mode to convert multiple colors at once by pasting one color per line.
cmyk(0%, 66%, 80%, 0%) → #FF5733
cmyk(86%, 11%, 0%, 7%) → #22D3EE
cmyk(56%, 38%, 0%, 85%) → #111827Hexadecimal output
Output is the 6-digit #RRGGBB form in uppercase. This is the most portable token for CSS, design tools, and configuration files. The conversion runs through sRGB and rounds each channel to 0–255. You can export the results as raw text, JSON arrays, CSS variables, or JavaScript arrays.
Profile-free approximation
The math does not use an ICC profile. The resulting hex code is a generic preview of how the ink mix would look on screen, not a calibrated match to a specific press. Fine-tune by eye or against the official sRGB value for brand-critical work.
