I would treat the dormers like the rest of the house. Body color on the shingles and trim color on the wooden trim.

^^^^^ What emmarene said.

First, congratulations on your new home! I can tell it's going to look outstanding when you're finished fixing it up. (In its current state it actually looks better than most of the houses being built today, which have zero charm.)

Now about the color choices: I think I'd want the shingled areas—sun porch and dormers, right?—to stand out from the main body color. What is the cladding material for the second story, btw? And is the roof going to be asphalt or cedar shakes? It's hard to tell from the second photo.

A thought on the shutters: Even though the first picture shows the house had shutters (at least at that point in time), I'm not sure they're what's best, aesthetically speaking, for this house. If you do hang shutters, just make sure they're correctly sized and fully functional—with real hinges and shutter dogs—and not just bolted to the house! It's amazing how little details like that can really set your house apart from the neighbors'.

I'm really interested to know your final choices, and PLEASE, post more pics as the job progresses!
