Name: Indigo Blue
The blue colour obtained from indigo plants is indigo dye (or indigotin as it is often called) together with small amounts of impurities. Indigo is insoluble in water, and most other common solvents, and will not dissolve with heat or stirring. The indigo vat is the traditional process by which the dye is made soluble.
