However, during last few decades, ecological concerns related to the use of most of the synthetic dyes, motivated R&D scholars all over the globe to explore new eco-friendly substitutes for minimizing their negative environmental impacts, and various aspects of bio-colorant applications (Fig. Also, environmental and aquatic preservation aspects forced Western countries to exploit their high technical skills in the advancements of textile materials for high quality, technical performances, and side by side development of cleaner production strategies for cost-effective value added textile products. As now public’s awareness for eco-preservation, eco-safety and health concerns, environmentally benign and non-toxic sustainability in bioresourced colorants, have created a revolution in textile research and development. Natural dyes were also used in clothings, as well as in cosmetic industry (Henna, Catechu), pharmaceutical industry (Saffron, Rhubarb) and in food industry (Annatto, Curcumin and Cochineal). The unique character of their works were the result of using different mixtures of dyes and mordants, as varnishes and lacquers responsible for cohesion of the pigments and protection of the layers destroyed by environmental effects. In the past, painters had used natural dyes extracted from plants, insects, molluscs and minerals for their paintings.
It affects every moment of our lives, strongly influencing the clothes we wear, the furnishings in our homes. Color has always played an important role in the formation of different cultures of human being all over the world. Nature has always dominated over synthetic or artificial, from the beginning of this world as nature was the only option for human being then, and now with advantageous characteristics of naturally derived materials over synthetics giving them priority.
