So we are a few weeks away from plaster on our build. Wife put a stop to a pebble finish. We toured a few pools local that were PebbleSheen by pebbletec. She didn't like the roughness of them "she hates our exposed aggregate patio hurts her feet" . So we are now stuck with a traditional plaster. Our plaster company will only do white or grey plaster do to colors modelling. She wants a blue pool I know surroundings will change color of water sometimes. We have blue/teal waterline tile. What I have found is white plaster seams to be clear water especially in a shallow pool Grey seams to be more blue water . Our pool at the deepest is 5'9". Grey looks to be a grey/blue color plaster. They have no grey pools local to look at. From pictures I think I would like grey over white. Help me convince myself and wife to go grey!
