Iridescent Paint Made from Bacteria

In nature, color occurs in two ways, as Artsy explains: “through pigmentation, where color appears the same from every angle, or structural color, where color changes according to interactions with light.” However, a new study exploring which genes are responsible for coloration has led to the discovery that flavobacterium (a bacteria found in soil and water) can be tinkered with to alter its color. Chemist Silvia Vignolini says the colors are “really metallic, similar to the color you see in peacock feathers.” Further, she predicts that adding a fixative to color can create paint.
