Anyone done it? Would it be too much? We have a very large hall stairs and landing space in an Edwardian house and I think it could look beautiful. It is quite a dark space when doors are closed but gets sunlight most of the day if we leave bedroom doors open. Have got the tester and the square I have done looks quite brown and murky making me worries about the same colour over a larger area. However, we did our bedroom in F&B light blue and the tester pot looked like an awful dull grey colour but all over the bedroom it looks stunning and much lighter. Hmmm...
