Back in the day, paint often got its color from the actual animal kingdom. Insects like cochineal and carmine gave us rich blues and blood reds. Renaissance painters used egg as a binder in tempura oil painting. Now, rather than using insects as the material, one company is using them as inspiration. And it has the potential to do a lot more than beautify.

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).

In short, this paint functions through structural color rather than chemical pigments or dyes.
