CIELAB to CMYK Converter

Convert a CIELAB colour to CMYK, with a live swatch and every other notation alongside.

To convert CIELAB to CMYK, paste your colour above — any recognisable notation is accepted, including named CSS colours — and every format is shown at once with a live swatch. CMYK is a print colour space, and the conversion is an approximation: screens emit light, ink absorbs it, and vivid RGB colours have no CMYK equivalent at all.

About converting LAB to CMYK

CIELAB was designed to model human vision and underpins colour-difference calculations. It is the reference space rather than an authoring one. CMYK is a print colour space, and the conversion is an approximation: screens emit light, ink absorbs it, and vivid RGB colours have no CMYK equivalent at all. Because CMYK depends on the ink, paper and press, a conversion without a colour profile is an estimate — send artwork to a printer in their profile rather than relying on a generic number.
