There's so much you can do on a fresh, white canvas. This room, in particular, is singing to me right now. Fresh, bright spring colors popping against a neutral ground. Tangerine, lime, and aqua clearly say spring.
Another key to the interest level: graphic patterns liven up the fields of color in the room. Here's how to get the look:
green pillows from Etsy seller Ruthscrafts
orange brooke pillow from Madeline Weinrib
jute rug from Pottery Barn
vintage art via ebay
