RGB to CMYK Converter

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

To convert RGB 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 RGB to CMYK

RGB gives each channel as 0–255. It is the same colour space as hex, just written differently, and adds an alpha channel as a fourth value. 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.
