Have you seen our bedroom? (I know you've seen the living room but can't remember if you got the tour...). We have one wall approx that sort of red, & the rest off-white (Roman White, iirc), with wood floors, & it looks lovely. (lots of the rooms have that - the living-room is two greens, the kitchen has pale blue with a red stripe, & my room has light purple with one very dark purple). I think all the walls either of the dark colours would be a Bit Much, but having one wall can be really nice.
