http://en.wikipedia.org/wiki/Blue
Blue pigments were originally made from minerals such as lapis lazuli and azurite, and blue dyes were made from plants; usually woad in Europe, and Indigofera tinctoria, or True indigo, in Asia and Africa. Today almost blue pigments and dyes are made by the chemical industry.
