Oh wow! Once my pebble was installed I didn't check back with the website! I think you've picked a beautiful color!
It's so hard to say about depth and water color. I know it intensifies the color, but it also depends on the surrounding colors. Sunbaby's pool is almost one depth or at least a sports pool depths. And her Blue Granite is fabulous! I love it. My pool has a 7' deep end which does bring out more of the blue, but overall in the bright sunlight, my pool looks very pale. I do get a lot of shade which is good for me. And there are times of the day that I love the Blue Granite.
I think you definitely made the right choice if you don't want pale. And with your tile - smashing!!! So don't worry - you're going to love it!!!
I can't wait for you to get your pebble! This is exciting!!!
