Hey Marla, pool is looking good!
Hey, have you guys been to QDI here in Houston? That's where we went to pick out our travertine and split face stone, they have huge courtyard with all the choices built outside on display. One of the travertines you posted pic of (Noche) is what we used and we got it from QDI. That piece you have is considerably orange, BTW, you know how it varies. But, I think the Colorado will look great with that glass tile. Master Tile is right around the corner from QDI and you can see all their glass tiles too. Highly recommend a trip to QDI, it's very helpful seeing all your choices on display and holding your glass selection up to the stone there in the daylight.
