Thanks for the suggestions. We have a Brewers and I hadn't thought of going there.
I have the decorator coming on Monday so I'm panicking now that I haven't chosen a colour!
Its a large room with big windows and high ceilings. There are big trees outside though which mean the room is slightly darker than it should be. I'm afraid that if I go too dark with paint that I will regret it. On the other hand I'm also afraid of regretting it if I'm not brave. I was going to go for Crown Etiquette but I'm worried that it may be too light. I want to avoid anything too cold or "baby " blue toned .
