I removed some built-in shelves in my house and had to put in new Saltillo tile in the spaces they were removed from. The new tile does not match the old. I understand that some of the older color is due to aging (it's about 50 years old) but I would still like to match as closely as possible. I have checked my local tile stores/dealer as well as the larger home stores and can not find a stain. My issues have been: 1.) space is too small for the company to come out and do, 2.) the stains they sell are either clear or far too dark and 3.) The one company I found that can match them insists that I would have to strip and restain the entire room to get a good match. Here is a picture of the tiles; the newer tile it the lighter color. Any tips on getting them to match?
