CMYK - These are the colours that four-colour CMYK printers use (i.e. cyan, a light blue; magenta, a pinkish purple; yellow; and, black inks). These are called subtractive colours, as combining them all gives the colour black. Subtracting one or more of these colours will yield any other colour. When combined in various percentages, these four inks will create an entire spectrum of colours, including those used in colour photographs.
