Just installed new pool and am thinking the PB might have used the wrong shade of grey. I chose a darker bluish water color which I was told was light grey. Pool has been built and is now about 12 days old and water is a little lighter and greener than I was hoping. Can anyone tell me how long It takes to achieve the final water color. The pool still looks great just really nitpicking at this point. The color I chose is attached as well. It is a buddy's pool from the same builder. I requested the same color. I looked at the fresh plaster on both as well and his was noticeably darker by a few shades.
