We are having our pool plastered with Diamond Brite. Our PB indicated that that there would be an upcharge of $4 per SF to go with Watercolors (i.e., Midnight Blue or French Gray) instead of the typical colors (i.e., Super Blue or Blue). This would mean about a $3000 additional charge. He suggested that the difference is not that dramatic and that we save our $$ and put that toward a paver patio instead. What are your thoughts on going with Midnight blue or french gray over say super blue (regular diamond brite).
