If you want something to absorb heat, then color it black. If you want something to give up or release it's heat efficiently, then color it light (i.e, don't paint it for Gods sake). All things considered equal (as in the density of the material you're dealing with), I would keep an IC as light a color as want it to give up it's heat not retain it - or for that matter - not gain additional heat from surrounding engine components.

But then, physics be damned. Dark vs. light colors may result in one or two degrees difference in intake air which case, BFD. Paint it something eyecatching like fuschia.
