NPT StoneScapes® Touch of Glass MIDNIGHT BLUE TOUCH OF GLS 1/2 Midnight Blue Pebble Pool Finish .5 Parent Kit. StoneScapes Touch of Glass Midnight Blue pool finish creates dark blue to dark blue/green water color depending on the depth of the pool and the pool surrounds and is comprised of modified white Portland cement which has been colored with midnight blue pigment, black, gold and white quartz pebble aggregates and a specialty blend of colored quartz highlights with Black and Cobalt Blue glass bead accents. The glass bead accents enhance the water color by adding additional pops of color and contrast that only colored glass bead can do. The beauty of this finish comes from the shade and color variations inherent in natural materials.
