Oooh, cant wait to see that one filled up. Bet it will be gorgeous.
When my new pebble was going in, to match my previous plaster which was a deep aqua color (a modified Tahoe Blue), I freaked! It was robin's egg blue. Awful. They had to sedate me. OK, well, they had to explain to me, about how the color develops. Sure enough, after it cured, and got acid washed, and the water went in... perfect!! Whew... I actually am right there with you. I'm afraid they may have done the acid wash and I missed it and this is the color...gulp
