Which water line tile did you use to match Lightstreams Steel Blue?

[Dori123]

I have read that spending $$$ on this tile for the water line is not a wise choice, as it is expensive and the sun doesn't hit the tile as well as it does on the shelf and stairs. So I'm curious as to what you all used for the water line. We are having a hard time finding a blue tile that is in the same color neighborhood as the steel blue (which we love and already purchased for the shelf/stairs).
Suggestions would be much appreciated!
TIA

Depending on your design (modern or not) you can use a black or dark or light stone looking tiles instead of trying to match a blue.
