If one side of a material is hotter than the other, heat can be conducted through. ... Incandescent light bulbs emit radiation because the wire within is heated. Color has no effect on conduction or convection. It does, however, affect radiation. Material looks dark if it absorbs most of the light that hits it.

Note that an object appears white if it reflects all colors, black if it absorbs all colors. Naturally there are gradients of color and therefore gradients of absorption. So, too, ... The darker the color, the less visible light it is reflecting and the more it is absorbing. The absorbed light is converted to heat. There is a...
