In the history of natural dyeing, India has a rich heritage of using vibrant colouring fabrics, paintings with the locally available colouring materials. These colorants were made from plants, animal extracts or minerals. During the medieval and early colonial periods indigoid blue, khoyar from acacia bark, range of reds from madder, burgundy from lac insects were mostly used in which the colour “last as long as the cloth itself”. Among the various types of natural colorant materials, plant extracted dye is widely used, some of which has also medicinal properties. In India, there are more than 500 varieties of plants that can be used for dyeing and printing. In Assam also, there are large number of dye yielding plant available in the forest as well as domestic areas. In this article, the author studied the different dye yielding plants of Assam and establishes more than 50 numbers of mostly used plants which are grouped according to the particular colour they produced. Though, natural colour has certain inherent drawbacks for large scale production, use of natural materials increases the value of a product and contributes to sustainable and eco-friendly environment.
