In the food, cosmetics and pharmaceutical industries, due to serious environment and safety problems caused by many artificial synthetic pigments, research has focused on processes for the production of safe and natural pigments from natural resources. Natural pigments can be obtained from ores, insects, plants, and microorganisms. Red, yellow and blue are basic pigments. Most research has focused on the yellow and red pigment production. However, study of the blue pigment is limited, probably because not many organisms are capable of producing blue pigments.
