The term basic color is mostly used in connection with the Pantone Matching System. The Pantone colors – since 2014 a total of 1755 colors – are mixed from 18 PANTONE basic colors in different mixing ratios.

These four new basic colors are PANTONE colors themselves, but are just as well used for mixing other PANTONE colors.
