I love a neutral pallet mixed with black or dark trims, and the odd colour pop (e.g I have a black and white staircase, white walls and an orange pendant light hanging over the stairs). My living room is newly decorated but it’s proving very bland with a beige couch, grey carpet and white walls! I want to add colour to the walls to break it up but without it being colourful per se. It‘s also a dark room so I want to keep the walls light. I was thinking possibly a deep dark green (like Rustoleum Serenity) on the fireplace wall and the rest a mid white like Little Greene Slaked Lime Mid (or Deep). Are ’feature walls’ too dated? Any other suggestions please?
