What Could Be The Next Great Source Of Pigments? Genetically Engineered Bacteria

"The model organisms used for [a new] study were colonies of flavobacterium, a rod-shaped bacteria found in soil and freshwater; the colonies were naturally a rich, metallic green hue. By altering the genetic makeup of the flavobacterium, the scientists found they could also change the color of the bacteria. Not only could they produce any color of the rainbow, they could control the intensity of each shade" - and the resulting pigments are brilliant and iridescent, like peacock feathers.
