Very nice color, madtv126. To answer your question, we wound up going with Aqua Blue PebbleSheen with broadcasted Shimmering Sea.
And this is the round-about way that we arrived at that decision:
The initial plan was to go with a light, smooth finish. I was looking at quartz aggregate, which has more durability than plaster but a smaller upcharge than pebble aggregates. It also complimented the stone and glass tile we were looking at. However, my husband and I decided that the quality of the application (assuming quality material) was probably the most important factor. The sub that we wanted to use installs PebbleTech, so we focused on the three lightest shades of Pebble Fina. Then three things happened. (1) We wound up scrapping our plan to use glass tile and went instead with a light ledger stone. (2) When we went to see our surface choice in person, the women said she was having her surface redone after a year. (3) We had to sign a disclaimer which made me realize that the mottling, streaking, and cracking issues that come up may be more of a feature than a bug. We could have gone with one of the white PF colors, but it was very difficult to find any pools to view - either in photos or in-person. The posts from people that had them or had seen them were lukewarm. Ultimately, I figured it wasn't worth having a blah shaded area or potential staining issues. And it definitely wasn't worth it if we had to pay a bigger upcharge for it. So at that point, we decided that the PebbleSheen (which was essentially the same price as PebbleFina for us) would be a more forgiving surface. Cue the obsessing over a whole new set of colors. Two of the lightest colors had an additional upcharge, so we wound up ruling them out - not enough bang for the buck. In the end, we chose between White Diamonds, Aqua Blue, and Blue Granite. Aqua Blue was the best fit for us in terms of shade, and when it inevitably fades some, it will fade into a shade that we're also happy with.
We also wound up getting a heat pump with a chiller, so I was not as concerned about going with a really light color to try to minimize the summertime bathtub effect.
It was super-helpful to be able to read all of the finish and color posts on the site - sometimes more than once - when making the decision. It was also super-helpful to get feedback from people - both in private messages and on this thread.
