I love the simplicity of chocolate brown and white, which looks great with a punch of solid color. Although they've used aqua blue, you could certainly use lilac, yellow, pink, green or any bright color to complement the richness of the dark brown and the busy pattern on the duvet and shams. I would actually love to see this bed and bedding against a colorful wall, or perhaps with a pair of brightly painted vintage asian night stands, such as shown below:
You could also use the night stands I wrote about in my other post and not even have to change the throw pillow shown on the bed! If you aren't into being quite this bold, they also have some great solid basics. I'm so excited to see stylish organic products hitting the mainstream market!
