Good Morning, new on here and freaking out a lot. Pool renovations start MONDAY. We’ve picked a glass tile called Melody in 1x2 which was very easy. Pictures show it as gray but in reality it is an iridescent pale blue and light gray mix. But picking a finish to match is scary. Contractor recommends an exposed aggregate from Freestone called Tropical Blue. I’m worried it’s too dark and if Freestone is the right choice. It’s a little rough! Help with any advice or pictures please.
