Our living room is about 19ft long by 12ft wide, we do get a lot of light in as there are patio doors at one end that lead out on the the garden & a good sized window at the opposite end. At the moment the walls are painted white, with the exception of one wall that has a pale grey brick effect wallpaper on. I'm thinking of taking the paper down & painting the wall in a navy blue colour. Only it's a bare wall, there isn't anything against it, no pictures hung or mirror, only the electric fire. Would it look odd with nothing on or against such a strong colour? I'd like to do it & have seen some lovely pictures on Pinterest but just afraid of taking some good wallpaper down & screwing it up!
