My first pick is the top set of diamonds. I like the idea of the diamonds being every 5th one or so. I will let you do the dimension and see what interval would work the best for your size pool.
Now my color pic is: 1st the top left (lighter blue), 2nd bottom right (blue with brown mixed in, 3rd top right (brownish) last bottom left (dark blue)
For some reason I don't care for any of the ones in the middle set. The colors just don't do it for me.
The bottom ones. I do like them but not sure they will work with what you are doing.
