I'm pretty much obsessed with gray paint, and am always hunting for ways to use it without the whole room going industrial and icky. This is a great example of gray done well. It's the hallway of Phoebe and James Howard’s Atlanta apartment—she decorated it; he designed the architecture and interior layout. The walls are painted Blue Hubbard by Sherwin-Williams.
