Many paints and pigments formed from chemicals have adverse effects on environment. Also dyes which are used for many applications need to be environment friendly. The paints are applied to households, not only for decorative purposes but also for their corrosion resistance. In food ingredients also colour imparts desirable pleasant look. Biocolours are nowadays used in majority of food items. Dyes are also becoming integral part of modern day life. There is no hair damage or scalp irritation because of dying the human hair by using plant derived formulations. Dye containing polymers are becoming a part of everyday life. There is need of novel non-toxic inorganic pigments in order to remove elements like lead, chromium, cobalt entering in the composition of usual pigments. Isolation of pigments with anti-bacterial activity from soil bacteria can also be carried out to obtain different colors such as yellow, golden yellow, red, pink, blue, green, purple and cream. Biocolours are mainly prepared from plant origins. They also work as antimicrobials, antioxidants. The current review summarizes research and studies on environment friendly synthesis of colour, pigment and dyes.

Key words: Paints, pigments, biocolour, formulations, disperser.
