It does help to see pools in person with the different pebble colors you are interested in, and we had a box of samples at home that we wet with water to see what tones and even pebble colors stood out. We had also seen some sample pools at a pool builder's office that used many different pebble shades within the pools, and that really helped us decide that it was important to us for the pool to look pretty at all depths - like our tanning ledge, steps and spa. For this reason, we steered away from grays because while it looked pretty in the deeper parts it looked like wet cement in the shallower parts. My color choice won't help you since it's a different manufacturer - Wet Edge Satin Matrix Tahitian Tropical. My pool builder said that we would be able to make some tweaking requests on our color choice too with Wet Edge. So if you love Aqua Blue but think it has too much black pebble for your taste, you could ask to reduce or eliminate that black and increase the white pebble. Worth asking about if you're 95% in love with a shade with one little exception!
