You might be better served by using the computer simulated colors. This would probably not hold true across different brand names, but should have some "truth" in it across the colors of any one company. Why? Since you don't know the sky conditions when the various photos were taken (clear blue, partly cloudy, overcast, etc); the angle of camera to water surface (and angle of sun to water); the exposure accuracy of the camera (some cameras are better than others); depth of the water (etc.). If conditions changed enough, these things could even affect your personal, on-site, impressions.

I gave you some feedback on one of your other posts about Stonescapes mini pebble. I know this wasn't one of the colors you asked about, but this is Stonescapes Tahoe Blue:

We were going to go with the Stonescapes Tahoe Blue but I decided I'd rather have Wetedge Technologies and switched. The Wetedge Satin Matrix Northshore Caribbean was installed yesterday on our new pool and while it doesn't have water in it yet we absolutely love the color of the Northshore Caribbean. Stonescapes is very nice also and my pool builder likes it a lot. I have a neighbor with it but not 100% sure of the color but it looks great. If I find out the color I'll post.

Did a complete overhaul on my indoor pool. Noticed that in the deep end very noticeable white streaks were forming. It has been only 30 days since it was filled. Please help. Contractor wants to cut out that section and put new pebble. Of course my fear is that it will never match. He does not think that draining and acid washing will correct the issue but i have been told by a couple of pool service companies that it will. Check out the bottom step too.. Any advice is much appreciated. I want to make sure I’m not being too picky too..
