The dyes extracted from natural sources like plant, animal and minerals are called Natural dyes.
Pharmaceutical, food and fruit industry wastes are one of the main sources of colourants which can be employed for textile coloration. Curcumin (Curcuma longa), a member of the family Zingiberaceae, is used in food recipes. Curcuminoid pigments are responsible for the yellow colour of turmeric.
