Hi, I have to decide of which color to put in our pool soon and it's a free form pool with waterfalls and tons of natural rock, so we want it to look somewhat natural. I want the color of the water to be medium to dark blue/gray and I'm trying to avoid a greenish color. We are going back and forth on Tahoe Blue and Tropical Breeze (and open to anything else that would look nice in the that setting) and would like to get your opinion. It's so hard because sometimes the Tahoe Blue looks really blue and sometimes kind of blue/green....can you post pics if you have either of these colors or if you've seen them in person, can you give your opinion. Thank you so very much!
