<graphics> cyan, magenta, yellow, key.
A colour model that describes each colour in terms of the quantity of each
secondary colour (cyan, magenta, yellow), and "key" (black) it contains. The
CMYK system is used for printing. For mixing of pigments, it is better to use
the secondary colours, since they mix subtractively instead of additively. The
secondary colours of light are cyan, magenta and yellow, which correspond to the
primary colours of pigment (blue, red and yellow). In addition, although black
could be obtained by mixing these three in equal proportions, in four-colour
printing it always has its own ink. This gives the CMYK model. The K stands for
"Key' or 'blacK,' so as not to cause confusion with the B in RGB.
Alternative colour models are RGB and HSB.
