We have an exposed brick chimney breast with F&B stiffkey blue either side on just one wall, which we love.
The rest of the room (and entire downstairs!) is painted in Dulux Ivory Lace, which was nice at the time but I'm tired of it (plus it looks tired too, after 5 years on the wall with young children)!
I quite like the idea of a pale "plaster" pink or another neutral(ish) colour with pink undertones, but I'm not sure whether I'd be mad to consider pink for a living room... the room is south facing and very light and airy, so it could take something a little darker than ivory lace without feeling oppressive...
