To produce blue, one would mix cyan and magenta inks, as they
both reflect blue while each absorbing one of green and red. Unfortunately,
inks also interact in non-linear ways. This makes the process of converting
a given monitor color to an equivalent printer color a challenging problem.
Black ink is used to ensure that a high quality black can always be printed,
and is often referred to as to K. Printers thus use a CMYK color model.
