We live in a world where colour is crucial. Colour has the power to influence our thoughts, alter our behaviours, and elicit responses. it also acts as a means of communication. Human civilizations, relationships, emotions, and memories are shaped by colours. Colours are irreplaceable.
Man has known the technique of colour application to improve our personality and the environment around us for thousands of years. Natural colours derived from plants, fruits, flowers, and some insects have been used to dye textiles. The standout feature of any textile is its colour. W. H. Perkins breakthrough of synthetic dyes in 1856 resulted in a wide spectrum of dyes that are colourfast, come in a larger colour range, and have brighter colours. As a result, “dye application” has grown into a huge multinational business; which runs even today.
Today we are paying the price for 150+ years of synthetic dyes consumption. These colours cost lives, not only human lives, but also the lives of the planet's inhabitants. These vibrant colours have a dark side since the colours have a detrimental influence on the environment.

So does that mean we stop using colours ? 

We look at how nature produces colours....
Observing how nature generates such brilliant colours without polluting the water or causing any ecological damage. In the absence of hazardous solvents, the microorganisms produce the same compounds that are synthesised in industrial settings today. Rather than exploiting resources, the goal is to integrate the production of Bio- dyes into a circular system that works in harmony with the natural ecology. Microscopic life also produces several different pigments including carotenoids, flavins and melanins as well as quinones and monascins along with violacein. Their uses include antibacterial, antioxidants, colour intensifiers, among other factors. Hence Microbial pigments is a promising answer to this global problem.
