I prefer Intellibrite lights from Pentair. As you know, the darker the finish the less the colors will show up. However, below are two pictures of a Turtle Bay Pebble Sheen pool (very dark finish) with a pool size intellibrite light and a spa size intellibrite light. We place the larger light in the main body, and the smaller light in the skinny swim lane wing of the pool. All the colors really pop with the 2 lights.

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: http://www.nptgonline.com/nptg_national/nptg_site/tilepages/inc38_dtl.html Aztec cobalt: http://www.nptgonline.com/nptg_national/nptg_site/tilepages/az606_dtl.html and Dakota rustic brick border: http://www.nptgonline.com/nptg_national/nptg_site/tilepages/dkb354dtl.html I think this is causing me more angst and headache than when I was picking out tile and colors for our home!!

Thanks everyone!!! I think I am going for the arctic white. I just had a guy come by who owns a pool service co. The pool ctr. hired him to clean the spa of the calcium build up from the water sitting stagnant during the remodel. He clearly is very knowledgeable on pools, and he said to pick the pebble sheen. He said if I plan to be in the house for a long time, that the pebblesheen is the way to go. He said it is a much better product and he thinks I will notice the speckles in the other product. He also suggested adding 5% blue quartz. He said he was just at a hotel pool with that combo and it was striking. He also said the blue quartz would look good with the tile and it makes the water just a little bit bluer. He is also going to service my pool. I am really happy I met him, because finding someone who can work the computer and understand the pool is difficult. He showed me how all of his clients are on his iphone and he can constantly monitor their pool conditions. Since I am redoing this pool so soon, I dont want to make any mistakes, so I will just bite the bullet and pay for the PS.

Hatteras Gray does not have any green hues. The coloring is mostly blue. In the shade, it has a deeper shade of blue. You could call CLI, who make Hydrazzo, and ask them about blending another of their standard colors to create the green your looking for. Jamaican Mist is a standard color which appears to have some green. You would have to look at the actual sample to make a determination. Their other line of plaster Krystalkrete, has some colors that require a blend of several colors for a particular result. So the possibility to blend Hydrazzo colors, is an option. They can create special order colors as well.
