There are many factors that influence the final pool water color including, but not limited to: pool depth, day time sun exposure, night time lighting placement, trees and landscaping, decking material and water features (i.e., fountains, jets etc.) Even water chemistry and filtration can affect water color. PTI cannot guarantee that a product sample or image will be an exact match to your finished pool for these reasons. In all cases, allow time for the initial curing process (approximately 30 days) before judging the finish or color.
