Why not try a buttery yellow wall paint. Dark rich blue velvet drapes, white chair rail molding (or band of white paint for visual effect), a very intricate white chandelier complete with crystals (maybe swap some clear crystals out for some blue ones.)
Yellow or Gold charger plates for under your blue and white dishes. At most dollar stores or Walmart, they have plate hangers you could hang larger pieces on the wall, use the dishes and vases on the table...Maybe pickup a White or Gold tea cupboard/jelly cabinet or a barrister cabinet.
OR, (had time to think about this and like this better), take your tallest piece and measure it. Then, add 2 inches to that measurement and measure that new amount down from the ceiling and mark it! Add a white shelf with a lip all the way around the room (make sure it has a lip of some kind). Still use a few pieces on the table if you can in order to bring the into the room....
