Aqua Blue with shimmering sea added. We wanted to go with a deeper blue (perhaps Blue Granite or Blue Surf), but our pool is only 5ft deep at its deepest point and those colors appeared more grayish in the shallows. We were also concerned about the Texas sun heating up the pool too much with a darker color. Happy with our decision--ranges from a powdery blue when overcast to a crisp light blue in sunlight. I am including a close-up of the spa bench, so you can see the color in the shallows with calm water, as well as a shot of the sun shelf (with some feet in it).

The nighttime picture is certainly not representative, but we were very curious what different plasters would look like when lit by colored LEDs, so maybe you will find it helpful (answer: every color except yellow looks wonderful; predictably, the yellow just looks green).
