A white surface is a good radiator of heat.
Shinny silverd surface
heat absober absorbs heat & refelector reflect it
Yes, it is. As dull and black surfaces are the best emitters as well as the best absorbers of radiation. Hope my answer is good enough to be stand up your question needs.
White marble, being white, is a good reflector of heat.
Material with low specific heat capacity and with blackened surface are good for radiators.

It is in fact the best radiator. Dull black is the best absorber and emitter. Then shiny black, followed by white, then silver. While the best reflector goes the other way around (silver's the best, then white, followed by shiny black, then dull black)

White is a good reflector of heat therefore it will absorb less heat than a dark surface.
A black surface absorbs the heat radiation and a white surface reflects the heat radiation
The shiny surface is a reflector, to reflect the heat outwards towards you.
More surface area to dissipate heat, the more exposed surface of a material the more place to 'let out' the heat
Lots of surface area - its designed that way.
