  Definition:Indigo dye is dye with a distinctive blue color (see indigo). The chemical compound that constitutes the indigo dye is called indican. The ancients extracted the natural dye from several species of plant as well as one of the two famous Phoenician sea snails, but nearly all indigo produced today is synthetic. Historically, indigo played an important role in many countries' economies because natural blue dyes are rare.
  Among other uses, it is used in the production of denim cloth for blue jeans. The form of indigo used in food is called "indigotine", and is listed in the USA as FD&C Blue No. 2, and in the European Union as E Number: E132.
