Actually the atmosphere DOES tint objects blue, but getting the right lighting is going to be tricky no matter what.Usually, you are going to have something in mind...that's the point anyway. That's why photographer's use filters(That would be cool to have btw).I think #1 does look more accurate. That sky looks pretty dark w/ the moon and that tower is up there so to me the blue effect would definitely be there.Having the brighter warmer tower while nice(in seperation of figure/ground)doesn't look accurate to me either.

No need to think outside the box....
