Help picking colors to tie things together?

Im looking at buying a house with nice dark cherry cabinets, black granite counter tops, tan travertine (spell?) flooring, and a little darker brownish carpet. I'm trying to figure out a paint color scheme that would work to tie these all together. The stairs banister is also cherry with wrought iron bars... the bathroom has antiqued hardware but lighter tile and the same brownish carpet... any ideas? tips? etc? thanks!
