On a hot summer day, white clothes seem cooler than other colors because they reflect rather than absorb sunlight. Other colors, such as blue or black, are subjected to a heating effect, as they absorb light. To circumvent this heating effect in color cooling films, the researchers drew inspiration from nanostructures in the wings of the morpho butterfly, which have a rich, bright blue color, but practically do not heat up.
