From RGB to CMYK
Screens emit light and mix colors additively in RGB, while printers lay down Cyan, Magenta, Yellow, and Key (black) ink subtractively. This tool computes the black channel first, then derives the remaining inks — a standard, device-independent approximation. Exact print color depends on your specific paper, ink, and ICC profile, so treat these values as a starting point. Conversion runs locally in your browser.
