Colors like red and blue not only indicate different wavelengths of light, but they also signify warm and cold. This relationship is an established design norm and permeates our daily lives through consumer products, home decor, and art. In this study, we investigated how color information predicts the warm/cold perception of the beholder. We asked participants to give warm/cold ratings to 1934 color photographs of surfaces from various material categories and built regression models that predict a thermal rating of an image from its color statistics. The results showed that the color-temperature relationship is shared by a wide range of materials, from natural foliage to man-made plastic. In particular, the values in a” (green to red) and b” (blue to yellow) axes in the CIELAB color space best predict people’s temperature ratings. Overall, color information explained up to 30% of variations in people’s ratings. Our results suggest that the color-temperature relationship is governed by the low-level color statistics and shared by a wide range of material categories.
