Which liner for the "lagoon" look?

We are starting 20x40 Pacific IG pool. This is our 2nd IG pool. (new house)
The first pool had vinyl liner with the tile look at the top and speckles down the side and bottom. The deck was BF concrete. A good pool with a traditional look.
We are doing the "mountain pond" style this time. (more free form) with pavers on the deck. The trendy natural-look if you will. In some of the pictures we see, the bottom looks darker and the pool looks more like a lagoon.
Any ideas which brand of liners they are using to achieve this look and the name of the specific liner itself?
Thanks,

Cal

I believe most liner manufacturers carry black or mottled dark liners. We replaced ours with a Merlin brand liner. I believe they had one like what you're looking for. Do a search online for pool liners and I bet you'll find a bunch of options. Sounds like it will be beautiful when its done - good luck.

Cal, welcome to this forum!!
What you need to do is see pools with the liner in question - a picturre should do, but seeing one 'live' is best. The little 'swatches' they show you don't give the 'full effect' of how the pool will look. Of course, different manufacturers have slightly different patterns, so see what the liner you're buying looks like in a pool full of water.
