Love the purple walls (I can't find the source of this image which is mighty annoying) I love the color scheme but rather in a bedroom or living room. Dark purple walls, gray wainscot, white ceiling and marble gray floor. Metal or silver details.
a coffee table can really make or break a living room- functionally and visually. It has to hold the items you need at hand (remotes, magazines, candles…) but also able to serve as a dining table & provide a place for food and drink.
