The current house we are working on has some pretty cool color combos. On the outside the siding is sandstone, the trim is a cream color, almost a little on the yellow side, and then the front door will be a rich blue color.
The inside alll the trim, ceilings and doors are white (like always), and in the living room and bedrooms the walls are sandstone. In the kitchen though we mixed it up a bit because it was so big of an area. White cabinets, white trim and ceiling, and then the two big walls are sandstone again and the two short walls are a dark chocolate brown. Turned out awesome! Again, if I ever find out how to put up pics I will..
