J. Weiser's favorite gray: Benjamin Moore Stonington Gray! There's a few others close to it if you like lighter or darker, but this was my favorite. It just looks like a true gray which I love, not too blue or green.
Fossil gray Glidden-painting our bathroom right now with this color! love it,has undertones of beige, looks great if you have tile to match with browns and gray in it. It is discontinued though so ask the associate at Home Depot to look it up! Very helpful!
