I'm looking to get rid of the dark green(!) walls in our very bright, East facing bedroom. It's a big space with huge bay window and high ceiling. There is a dark blue, not navy, carpet we're not replacing as it's too good, oak fireplace with neutral tiles and a dark green splashback behind the sink, but I'm not really bothered about that as you don't really notice them. We have an oak bedframe and oak furniture. Any suggestions?
