So my pool is about halfway filled. The color of plaster I picked is Crystal Stones Caribbean Blue which is a blue base with black and tan pebbles. It looks so green to me right now! I wanted more of a gray blue color. Will the color change when the chemicals are added to the water? Do newly installed pebble finishes change a little bit after water is in them for awhile? Do I just need to calm down and reserve judgement until the whole thing is full?
