We have bought a fixer, its a split level home. The kitchen, dinning and living room are all in one space, and it is also open to our basement family room. The one large wall connects the basement to the upstairs. I have already chosen a wall colour for the family room (Basement) Which is French Press AF-170 from Benjamin Moore, which will work perfectly with the plaid wallpaper that will be on the accent wall in the basement. My dilemma is the large wall that goes upstairs. What colour should it be?
