Clothing Color Effect as A Target of the Smallest Scale Climate Change Adaptation

Abstract

The reflectance in terms of clothing color is important for outdoor thermal comfort. Since 2011, we observed surface temperatures of polo shirts of the same material and design but different colors; the shirts were hung in unshaded outdoor open space. Brightness of color is an important determinant of solar radiation albedo, however reflection performance in the near-infrared (invisible) band is also an important determinant of surface temperature. The maximum difference between green (higher) and red (lower) was almost 5 - 10 °C and was greatest when the solar radiation was strong.
