The “Structural” Color That Comes From Butterflies And Could Cool Cities

Cypris Materials has created a paint inspired by blue morpho butterfly wings, which get their color from blue lightwaves reflecting off the nanostructure of the wings themselves (up close you’ll see they’re actually translucent). Like butterfly wings, Cypris’ paint works through reflection, so color comes from particular lightwaves that reflect off the nanostructure of the paint. In short, this paint functions through structural color rather than chemical pigments or dyes. – Fast Company
