We have settled on Picasso Blue to our pebble from Wet Edge Signature matrix and will have Ivory Travertine. We are considering the waterline tile of NPT Royal Seas - Royal Blue, but are not certain if it is too dark of a tile. We would love any suggestions for a tile that would look great with Picasso Blue and Ivory Travertine or if anyone has seen/used the Royal Blue waterline tile, would it look good with the other color selections?
