India has a vital monopoly in their production and application of natural colors obtained from leaves, flowers and fruits. After the invention of synthetic dyes, natural dyes were forgotten and abandoned as a part from history because of its negligence. Due to the environmental and health hazard problems caused by the synthetic dyes, now people are more concerned about the usage of natural dyes during the last two decades. Botanists have identified more than 450 dye yielding plants that naturalized in India. The natural dyes are fast in staining, long-lasting, renewable, bio-degradable and eco-friendly. Now-a-days, natural dyes have entered into the textile, food, pharmaceutical, cosmetics, fiber, leather and paint industries. In the present study, the usage of the dye obtained from Annatto (Bixa orellana) is evaluated.
