Convert RGB colors to CMYK percentages for print design, with a live preview.
RGB is an additive color model used for screens (Red, Green, Blue light combining to white), while CMYK is a subtractive model used for print (Cyan, Magenta, Yellow, Key/Black ink absorbing light). This conversion uses the standard mathematical formula and is a close approximation — actual printed color also depends on your printer, paper and ICC color profile, so treat this as a starting point rather than a color-managed proof.
