As far as I've been able to tell, her deckhouses (most of them, anyway) were painted white at least on her maiden voyage. I chose this scheme when examining a photo of Maury in the book "The Only Way to Cross". I suspect that her deckhouses were painted brown later, possibly because of problems with soot.
As for the funnel bases, I've heard brown (and tend to agree with it,) but also gray, at least on her maiden voyage. It's worth researching, anyway.
