Abstract
The lack of color diversity is the fundamental problem inherent in the radiative cooling system, which raises practical issues of eye safety, light pollution, and aesthetics. In this work, we show a breakthrough for colored radiative cooling by experimentally demonstrating that sub-ambient cooling under direct sunlight is possible for all colors, including black. The key principle is thermal non-equilibrium between color and cooling parts, which can potentially serve as a new avenue for radiative cooling applications requiring diverse color expression.
