I'm trying to get a terrain piece painted and am a bit stuck at the moment. Early
WIP picture:
The question I'm stuck on is which color to paint the bridge. To explain:
I have nice, neutral greys on the concrete and the ship's hull, similarly neutral browns (albeit lighter than they are at this point) for the ground and a touch of color with the red part of the hull. Additionally I'm thinking of painting the large pipe in the wall cutout red as well. The bridge is made of metal which will give me some dulled silver and rusty brown/orange. I intend to add a few yellow and black warning stripes where appropriate, such as by the ladders.
So far I'm pretty happy with the color selections. Mostly neutral and muted so as not to detract from the actual models on the board, with a few spots of color to make it look interesting.
What to do about the bridge, though? It should obviously be painted so it doesn't rust (worked out well, didn't it?

). Conventionally I'd say a light green/olive, or railroad bridge green as I call it, is the default for these things, but I don't know. People love the combination of red and green for some reason. I don't One as a main color and the other on a few small bits? Sure, fine by me. But both in large quantities? Not sure that's for me.
Any input or opinions on this would be appreciated.
It's kind of hard to see in this picture, but the bridge support and pumping station are connected by a large pipe. I'm completely undecided on that, too. It's not a big deal if it's just silver, brass or completely rusted, but if it helps this could serve as space to bring in a contrasting or complementing color.
