The term basic colour is mostly used in connection with the Pantone Matching System. The Pantone colours – since 2014 a total of 1755 colours – are mixed from 18 PANTONE basic colours in different mixing ratios. The 14 original basic colours had a four colour extension  after the abolition of PANTONE GOE. These four new basic colours are PANTONE colours themselves, but are just as well used for mixing other PANTONE colours.
