Does anyone have white pool grout? How is the maintenance? We just installed a glass tile that is a mixture of clear, iridescent and cloudy glass tile (blend is called pamper) that comes off as creamy, and light with a slight bit of sparkle. Depends on how the sun hits it. Photo below is an evening shot but in the sun, the tile could look almost white/creamy. I found a TEC power grout called Pearl that closely matches the combination but I think the tile dies with it. Another TEC color, Standard White, makes it pop a little but I am worried it may contrast too much and am concerned about the maintenance. I tried a third, Sterling, which is a light gray and it looks ok, it can go but isn't as creamy as it should be.

The photos are ungrouped and represent two different angles.

Would love your input today as we need to grout tomorrow. Stone is a grand travertine. Thank you!
