Hi! We just laid this full color Bluestone-like porcelain tile in our screened in room and I need to choose grout. I definitely want a contrast hence the lighter colors. Which one of these four would you choose? From top to bottom colors are Mapei moonbeam, eggshell, frost, and avalanche. Do not want it too stark or to blend too much? Thank you!
