black and textured

Black absorbs most of the incoming solar spectrum, and a textured surface traps light and reduces specular reflection (increasing absorptivity and emissivity), so it converts more solar energy into heat transferred into the room. White or smooth finishes reflect more sunlight and so heat the house less.
