Colour has always fascinated humankind, for both aesthetic and social reasons. Throughout history dyes and pigments have been major articles of commerce. Manufacture of virtually all commercial products involves colour at some stage, and today some 9,000 colorants with more than 50,000 trade names are used. The large number is a consequence of the range of tints and hues desired, the chemical nature of the materials to be coloured, and the fact that colour is directly related to the molecular structure of the dye.
