Navy Blue. Ref # 508

For practial and aesthetic reasons navy blue glass tile is a very popular choice for covering underwater pool surfaces. Other colors can be used underwater but water absorbs dark blue light quickly, so colors appear to change with depth. This is why lakes and clear coastal waters appear blue to us. So blue is the ever-popular choice — and there’s nothing wrong with trying to put a little bit of tropical paradise in your backyard.

Dark glass tiles darken the appearance of water, making it appear as though the pool or spa is a sheet of glass.
