Sun:
We have Blue Granite Pebble Sheen, and we love how it sparkles in the sun and has great color of water. I don't think you will regret the choice at all. I should tell you, I wrestled with the decision too, and worried about choosing a color too dark, too light, too turquoise, too green, too windexy blue, to anything. I looked at a lot of pools here on this site, and out on GardenWeb, and basically so many galleries from PB's. I kept coming back to Blue Granite, and with the tile you have already chosen, Blue Granite is going to look rich. Now take a deep breath, and go enjoy your cruise. The rain will surely be gone by the time you return, and it will be POOL time!
