Blue Wall for Frame Collage

I saw this in the Pottery Barn magazine and I fell in love! I later read that if you have a wall that has a collage of black and white photos, painting the wall blue will compliment the gray's in the photos so nicely. Brett told me that we have to finish painting the office before we take on ANOTHER paint project. So I'm waiting patiently and trying to finish the office as quickly as possible.
