Colors that are put down on various printing materials are called subtractive
colors. Inks are an example of subtractive colors, as the inks act as filters,
subtracting components of white light to create colors.
Subtractive color primaries are yellow, cyan and magenta. If mixed together,
they are supposed to make black, but because of impurities in pigments
usually make a muddy brown color.
To compensate for this failure, printing systems usually use black ink in
addition to the subtractive primaries to complete their
gamut of reproducible
colors.
