Subtractive color

Color made by inks or paints absorbing light. Cyan, magenta and yellow combine toward black; print works this way.

Also called subtractive color mixing, subtractive colour

Subtractive color starts from white paper and takes light away. Each ink absorbs (subtracts) part of the light that would otherwise bounce back to your eye.

Cyan, magenta and yellow are the subtractive primaries. Overlap all three and you get a muddy dark brown, which is why printers add a fourth ink, black (the K in CMYK).
