About this conversion
CMYK is the subtractive color model used in printing: cyan, magenta, yellow, and key (black) ink percentages. Screens use additive RGB light, so converting between the two is an approximation. The result is useful for reference, but final print colors depend on the printer's color profile.
OKLCH is a modern, perceptually uniform color space supported in CSS: lightness (0-1), chroma, and hue. Unlike HSL, equal changes in OKLCH values produce visually equal changes in color, so palettes and gradients built in OKLCH look more even to the human eye.
To convert CMYK to OKLCH, the color is first interpreted in the sRGB color space and then expressed in OKLCH notation. Paste a CMYK value like cmyk(88%, 36%, 0%, 0%) above and copy the OKLCH result. The conversion happens instantly in your browser, and nothing is uploaded.
Note that CMYK conversion here uses the standard formula without an ICC color profile. The values are a good reference for matching screen colors to print, but the exact printed result depends on the printer, ink, and paper, so always confirm critical colors in your print workflow.
