SunStone Colors? Help?!

We have been having an extremely difficult time from the manufacturers, distributors, and our pool company trying to figure out what a water-filled pool would look like with particular aggregates that we are considering.

We want a dark bottom and not one with blues like you see in the Carribean, but more natural, lake-water type in color. Essentially we have narrowed our choices down to SunStone Caspian Sea and Smoke colors. We have seen pictures of a Smoke pool but not of Caspian Sea. We understand that they are similar in darkness but Caspian Sea has blue flecks and Smoke does not.

Does ANYBODY have a picture of a Caspian Sea pool? We want to make sure it doesn't look like Mediterranean Blue and, regardless, that it will be something that we like.

I am fully aware that pictures can be deceiving, etc.
