Hi, we're looking at either Pebble Sheen or Stonescapes Mini Pebbles, depending on the PB we go with. We really want a true turquoise blue water color, verging on teal blue. The online wisdom is that you must go with a tan or sand colored finish to achieve this effect, but the PBs we've talked to say this finish results in a very green looking pool, with an algae-like appearance (we definitely don't want that!), at least under the intense sun of Arizona. White pools seem too washed out and pale for our taste. Stonescapes Tropics Blue appears too dark in the photos we've seen. Pebble Sheen Aqua Blue may not be turquoise enough, as people have said it's similar to Pebble Fina Bella Blue, which we've seen in person and is WAY too blue. Can anyone recommend finishes that will give the effect of the Caribbean Sea? A bright, intense turquoise blue that goes teal in the shade? Thanks!
