With the development of radiative cooling research and the improvement of cooling effect, the practicability and application range of radiative coolers have been widely concerned. However, conventional radiative coolers typically come in white, which can be undesirable due to aesthetic reasons and potential light pollution. Luckily, a colored radiative cooler (CRC) has been developed and demonstrated as a solution that offers both vivid colors and impressive radiative cooling performance.
With the notable development of radiative cooling research and the continuous improvement of cooling effect, its practicability and application range have been widely concerned. However, conventional radiative coolers typically come in white, which can be undesirable because of aesthetic reasons and the potential of light pollution. Fortunately, a colored radiative cooler (CRC) has been developed and demonstrated as a solution that offers both vivid colors and impressive radiative cooling performance. In this perspective paper, the state-of-the-art colored radiative cooling technologies are reviewed. Starting with the brief introduction of the fundamental principles of radiative cooling and color appearance, the mutually restrictive relationship between the color appearance and radiative cooling effect will be dis-cussed, followed by the balanced design strategies. Then, the emerging materials and structures of different coolers will be discussed from the point of view of photonic crystal-based, nanoparticle-based, and fiber-based CRCs. Finally, conclusions and prospects are outlined to further promote the develop-ment of CRCs.(c) 2023 Elsevier Ltd. All rights reserved.
