CMYK to OKLCH Converter

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

To convert CMYK to OKLCH, paste your colour above — any recognisable notation is accepted, including named CSS colours — and every format is shown at once with a live swatch. OKLCH is perceptually uniform — equal numeric steps look like equal visual steps, which is why it produces far better colour scales than HSL.

About converting CMYK to OKLCH

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. OKLCH is perceptually uniform — equal numeric steps look like equal visual steps, which is why it produces far better colour scales than HSL. 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.
