RGB to CMYK — How it works

How RGB to CMYK conversion works

RGB is used for screens (additive light); CMYK (Cyan, Magenta, Yellow, Key/black) is used for print (subtractive ink). Conversion approximates how the same color would be reproduced with ink: first RGB is normalized to 0–1, then K (black) is derived from the maximum of the inverse of R,G,B, and C,M,Y are computed from the remaining ink needed. Values are typically expressed as 0–100%.

Example: Pure red RGB(255, 0, 0) → CMYK(0%, 100%, 100%, 0%). Use the tool above to convert any RGB color to CMYK for print workflows.
