We’ve decided to tile our reflecting pool. It’s cement which looks green when the water is in it, but not so pretty when it’s empty all winter (for our Colorado weather). I need help in picking a tile color. The feature is in a Mediterranean-style courtyard. I thought green tiles, but when the pool is empty, will it look too different from the surrounding patio? Will grey look too much like the cement we have now? Photos are attached to see what we have. Thanks for any suggestions!
