Painting in Gray

As Josh and I think about painting our 3rd bedroom a beautiful, simple gray, we received a caution from some friends who tried the same thing.  They said they painted their room gray and in the end, it just looked like a light blue, lame.  To that end, we've been carefully considering what shade to choose for our room and I recently found this excellent post from a one of my new favorite blogs Colour Me Happy.  Definitely a blog that's right up my ally, but this post in particular is worth reading if you'd like to ever paint anything gray.  Read the article here.  
Now I know exactly which pantone to pick to get the walls to look exactly how I want!
