Because of their biocompatibility, ecological advantages, and extensive uses in many sectors, such as the food, cosmetics, pharmaceutical, and textile industries, natural floral pigments have attracted a lot of interest recently. The intricate biological processes required to synthesise blue dyes give them a unique significance among these pigments since they are so rare in nature. Here we take a look at what's new in the field of floral crop blue pigment extraction, characterisation, and applications. It delves into the chemical make-up of blue pigments such anthocyanins and new ways of extracting them, as well as the molecular processes that control their colouration. The article also discusses the difficulties of keeping pigments stable and provides some ideas on how to improve extraction efficiency and find new uses for them in industry. Improving extraction techniques and increasing the economic viability of natural blue pigments are crucial in meeting the increasing demand for environmentally friendly and all-natural colourants.
