Now I know the blues don't match either of the pieces of furniture nor do the 2 blue pieces of furniture match each other. I would never allow this in my own house but that's the beauty of the mini world... you can do what you want. To the folks who visit my house (none of whom participate in this hobby), they'll be too goggled by the whole package to be as nit-picky as I am.
Rest assured, I am going to get rid of the green marble in the fireplace. This was a HLobby scratch-n-dent for $2.99 so I have to fix the wood, anyway. I think I'm going to go old ivory-ish.
