Polos26, I took the pictures for you last night. However, I can't find my card adapter to upload the pics onto my laptop. As soon as I find it, I'll post the pictures for you. As for a description of the color, I'd say it's a VERY dark gray color, the seams on my city are blue tinted, so dark gray with a blue tint. In some lighting, it's almost black, in others, it's almost gunmetal with a bit of a sheen to it. It's very beautiful and more unique than black!
As lordguinny said, there are quite a few threads comparing the various colors, so you may want to look at them in the meantime.
