Colorful surfaces for radiative cooling

Daytime radiative cooling has attracted extensive research interest due to its potential impact for energy sustainability. To achieve subambient during the daytime, a white surface that strongly scatters incident solar light is normally desired. However, in many practical applications (e.g., roofing materials and car coatings), colored surfaces are more popular. Because of this, there strong desire develop colorful cooling. We summarize general design criteria with different colors discuss limitations performance. Major efforts on this specific topic reviewed some suggested topics future investigation.
