A pigment is distinguished from a dye in that a dye is fully disolved in the medium whilst a pigment is distributed through the medium in suspension. Dyes may be turned into pigments by fixing the dye onto an intert base, colouring the base. The dyed base will then be finely ground and suspended in the relevant medium.
