Certain vibrant colors found in nature, such the blues and purples in bird feathers and butterfly wings, are created not by pigments but by physical nanostructures that interact with light, a phenomenon known as structural color. Such colors are often shimmery, and the reds and greens that researchers have tried to produce using structural color typically carry a blue tint. These properties limit the application of structural color in coatings and paints, where pure, matte . . .
