Some sources suggest that the K in CMYK comes from the last letter in blac k  and was chosen because B already means blue.he CMYK model works by partially or entirely masking colors on a lighter, usually white, background. The ink reduces the light that would otherwise be reflected. Such a model is called subtractive because inks subtract brightness from white.
