I like the grayish tiles you just added. Either of the two look fine to me.

Thanks Design Fan. Do you mean the two on the right?

Yes, mine are very similar. i like blue, BUT as I said, it was very unforgiving re hard water deposits. I’ve had the light gray for 6 years, shows some evidence of water deposits but not obnoxiously so like my cobalt blue did, at first glance no one would even notice. The only location where I notice it is at the waterfall wall coming from the spa. Mine are similar to those on the right.

I have had glass tiles in my pool since 2003- the pool plaster needs to be replaced- but the tiles are in great shape.

I meant the two lighter ones on either side of the Pebblesheen as they go better imo with the beige-er travertine.

I used a darker slate tile at the water line but my gunite pool has bluestone patios and a light gray finish plaster.

Tile color lighter the better to see what is on the bothom of the pool. things crawl, fall in pools since the location is a open sight. unless it is covered daily /nightly all kinds of critters manage to end up in the water/pool and cannot get out. just speaking from experience you might want to consider that humans are not the only swimmers in pools.

trim around the perimerter can be a differect color. Summer weather can support a lot of action by the pool but maybe not a lot of activity during the cooler months of the year.
