Hello! I'm moving into a new office with a large, beautiful arch that I would like to use as a feature. I'm quite new at design ideas, but am wondering about painting the wall on the inside of the arch a grey (similar to the colour at http://is.gd/DmQhPQ), but am struggling with what to paint the rest of the walls. I'm not set on the grey for the inside of the feature, but would welcome all ideas!

Do you think grey would work inside the arch? If so, light or dark? I am in the UK so will likely be buying from Dulux paint. Should the wall around the feature be a different colour to the other walls in the room? And what about the ceiling? Can you tell I am new to this?!

The floor will likely be a dark oak ( http://is.gd/UtnDkv), but would also welcome suggestions!

Thanks so much,
Rich
