I think you 'll find a ship in dry dock will have the water inlet and outlet grills painted. A couple of reasons for this, the antifoul paint prevetns the build up of critters that like to stick to the underside of boats and ships, which have to be sandblasted off in refits and can clog up water intakes, and secondly, unpainted brass inwater will corrode and over time break down in strength causing breakage and other nasty bits to get in your water cooling system. Oh and also part of the second reason, when unpainted may turn green, look at the roof of the Canadian Parliament buildings in Ottawa, green right, nope, thats unpainted copperplating, and they left it like that because they thaught it looked good, hmmm .

There's a third reason as well. The hull of a ship is spray painted. The grills just get sprayed along with everything else. There wouldn't be any reason to go to the effort of masking them off, or painting them a different colour. The grills of modern ships are made of steel, so would just rust if left unpainted. I guess WW2 ships were the same.
