	Tuning colored top layer in the bilayer cooling paints. (A) Using more selective dye as colorant to further improve the solar-infrared reflectance of the bilayer sample. (B) Changing the top-layer thickness and mixing Sudan Blue dye with Perylene Black dye to change the color shade of the bilayer cooling paints. The inset photo shows that the color gets darker after increasing the colored layer thickness from 20 m (left) to 60 m (middle) and adding Perylene Black (right). (C) By using poly(methyl methacrylate) (PMMA) binder in the top layer, a glossy sheen can be achieved, while with P(VdF-HFP) binder, a matte texture is achieved. (D) The bilayer concept can also be extended to fibers, which could lead to its potential uses in textiles. Photo credits: (C) J.M., Columbia University; (D) C.-C.T., Columbia University.
