black will actually radiate heat more readily than any other color or raw metal. THAT is why radiators are painted black. I think there is a company called Eastwood or something that makes specific paints for rad/IC.

A while back I came accross this right here on the forum. I didn't believe it at first either, but there was enough evidence to convince me. I remember someone said they did an experiment by putting two pieces of metal in the stove, one painted black, one raw. Then they took them out at the same time and measured the temperature loss over time, and the black one loss heat more readily than the raw metal.

a light spraying of any color won't hinder performance. if you saturate the i/c it will act like a thermal barrier, thus keeping heat in, and i'm not talking about the fins. spray it flat black and make a duct for it, you'll be 100% bueno.

i might be talking out of my *** here, but i think it was like this... its not nessasarily black that radiates heat the best... its whatever color radiates ir the best... which usualy has nothing to do with the actual color of the paint, since you wont be able to "see" a logical connection to what radiates ir the best
i think the trick is to use paint that radiates ir very well... that way it will radiate the heat the best...
wow, that sounded really jumbled, but i dont feel like rewriting it... basicaly you are looking for paint that has a very high thermal conductivity, and that will radiate strongly in the ir spectrum... if its black then thats a plus

Volvos have radiator coatings that clean the atmosphere. It would not surprise me one bit if they had one that could cool a little better.
BTW, a GN tuner by the name of Tony DeQuick has been black powdercoating intercoolers for years and has never seen more than a tenth of a percent drop in efficincy, and his are coated all over. I think the IC will be fine with a good black coating.

if painting/coating an i/c makes it loose heat faster, it will, indeed, get hot faster too. if the coating act as an isolant, it will takes more energy before it will change temperature. this is true both way, from cold to hot, hot to cold

Two points:
1) Nobody here has actually painted their IC black and measured the intake temps before and after. I plan to change that soon.
2) Mazda changes from unpainted intercooler to painted ones, so there must be something in it.
