I lied

I said we had chosen our countertops and paint.  Well, after I painted six different blue grey colors on a board, we went back to Ashfield stone to match one of them to our stone. We picked a color, but changed the stone.

Crowsfoot and Ben Moore Philipsburg Blue

We will use the quicksilver in the bathrooms with white vanities and a "blue slate" ceramic tile, which is an amazing match. Once again, photos don't capture it.
