My son & DIL are looking for a backsplash tile that give a subtle bit of color in a blue/gray shade. I have used Waterworks ice water handmade tile in the 3x6 but can't seem to find it for sale anywhere.

Did they stop making that color? I have a huge box of leftovers.

Is there another brand and color similar to that subtle kiss of blue gray? WOW in duck egg was similar when I was looking. Any others?
