We don't have flagstone but our tile is Slate Valley Ginger which has a lot of grey and brown tones in it. (Mkg Lauderdale) I really like our choice. Here's some pictures..... Good luck choosing!

Love that tile color! Do you know the manufacturer of that tile?

Thanks! Manufacturer is Lauderdale. They also have a few other colors. (I believe one is mainly beige and the other is more brownish color.)

Think it was called Pietra Series, National Pool Tile. 3m is Cayman Green/Blue Blend

Thanks Jimbar...I've long admired your pool. Is that the Tuscany Pietra Azul tile (there's no Pietra series in my catalog, just pietra color). That's one of the ones I'm considering, along with Inca blue:

Aztec cobalt:

and Dakota rustic brick border:

I think this is causing me more angst and headache than when I was picking out tile and colors for our home!!

My bad, company is Mastertile (formally International Tile). I called my PB and he said the Pietra Series may be discontinued. You may want to call Mastertile if you are really interested. It was called the Pietra Series and the color was called BLU (although its really a darker gray and tan)
