WASHINGTON, Aug. 4 -- Optica, formerly the Optical Society, issued the following news release on Aug. 3, 2023:
On a hot summer day, white clothing feels cooler than other colors due to reflecting--not absorbing--sunlight. Other colors, like blue or black, will undergo a heating effect as they absorb light. To circumvent this heating effect in colored cooling films, researchers drew inspiration from nanostructures in butterfly wings.
