so many shades of gray...as in paint

The house is in pretty good shape, aside from still needing some paint in the upstairs and foyer - so we started thinking about colors on Wednesday. We realized we love gray. I never really felt so attached to a color, but honestly I would paint the entire interior gray if I could. I think it is such a smart color. It goes with anything (aside from brown) and even though it is in the black family, it can really brighten a room (depending on what shade of gray you choose). My husband and I laugh because we don’t want our house to be fifty shades of gray (ha-ha), but we do really love the color. I think the foyer will end up gray, but the rest of the rooms upstairs will be jazzier colors used for accent walls. We have vaulted ceilings in the majority of our top level, and don’t think we should paint an entire room one color…it is a whole lottah wall. I will let you know what we end up choosing, but my front runners are purple for the spare bathroom, blue for our bathroom, and a spicy red for our bedroom. I don't really care what color we paint the office and think we should pick something semi-reserved for the spare room.
