I don't believe that it does. If this is true, it could be that black is a natural color for the sort of material (cast iron) that radiators are likely to be made of, while a white radiator probably has an insulating layer of paint on it.
A black body will radiate heat faster than a white body. This is because black surfaces absorb more light and heat energy compared to white surfaces, leading to faster heating and subsequent radiation of that heat energy.
No, white surfaces are not good radiators of heat. White surfaces are better at reflecting sunlight and heat, which is why they are often used in hot climates to keep buildings cool. Dark surfaces, on the other hand, absorb and radiate heat more effectively.

Black surfaces absorb a wider range of wavelengths of light compared to white surfaces, which allows them to absorb more energy and heat up faster. When black surfaces absorb heat, they also emit it at a faster rate due to their higher emissivity, contributing to their faster heat radiation compared to white surfaces. White surfaces, on the other hand, reflect more light and heat, which reduces their rate of heating and heat emission.
The reason something looks black to us is because it reflects less light - therefore, the light is absorbed. The energy of the absorbed light, of course, heats the object up. Please note that black objects also tend to emit thermal radiation faster - so if there is no sunlight, they will get cold faster.

Yes black ink radiates more heat than white paper. This is because more heat is absorbed by black ink more than white paper and it is required to radiates more heat due to its heat capacity
A lamp or a flame radiate light. (as do incandescent bodies) A radiator radiates heat, (as does any other hot body) And speakers or horns radiate sound ( as do any vibrating bodies)

Black because it absorbs all the heat whereas white reflects the heat away so black is a better heat insulator. Help this helps :)
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)
Heat - generated by your metabolism. The colour of your clothes is not important save that a black shirt will radiate heat from you more easily than a white one, but will absorb more external heat such as from the Sun.
Darker surfaces tend to radiate heat more effectively than lighter surfaces. This is because dark colors absorb more light and heat, which then gets re-emitted as thermal radiation. So, a dark or black surface would radiate heat more efficiently compared to a light or white surface.

Car radiators have fins to allow the flow of air to enter, but as well as having a bit of protection. If it didn't, you would have a car with a hole in the front. Also, they are black to absorb and radiate heat. Black bodies radiate heat better so that is why they are black. The thin fins improve the overall surface area so that heat is dissipitated to the ambient efficiently. Hope this helps.
