NPT StoneScapes® Touch of Glass TAHOE BLUE TOUCH OF GLASS 1/2 Tahoe Blue Pebble Pool Finish .5 Parent Kit - StoneScapes Touch of Glass Tahoe Blue pebble pool finish creates medium blue to blue/green water color and is comprised of modified white Portland cement which has been colored with blue/gray pigment, black and gold natural quartz pebble aggregates with black, ice and sky blue glass bead accents.
