We've just moved into a 10 year old home and would like to freshen it up a bit. The Mr. says no to a complete repainting of the interior, so I thought I'd paint a couple of accent walls. Existing walls are 'Lightweight Beige' from Sherwin Williams. I took a piece of floor tile to SW and with help from the sales guy, chose a shade of gray we thought would work, but on the wall it looks a bit like the side of a battleship I'm afraid. I don't want to hire someone for such a small decision. Any ideas of a good gray to go with this tan and the tile pictured? I might paint this hallway but mostly I would like to do the very light and bright entryway - this was just the best pic I had showing wall color and tile. Thanks!
