Try these: http://www.missiontilewest.com/styles/revival/boards/dealerinfo.html and these (make sure you scroll down by using the thin red bar on the right): http://www.missiontilewest.com/ These are the tiles I am hoping to use for my kitchen back splash, but while doing an image search, came upon this thread. They will customize the colors in any of their deco liners, but they are not cheap (approx $12.95 for a 1 x 6" custom liner tile). I copied their revival line drawings and mocked up different color combos on my computer to see which pattern and which order to do the colors. I am 99% sold on using these but the cost is making me do one more search to see if I can find similar.

Arto Probably Charcoal and Natural Gray -- 18x18?

The tile pro I have used could do that work, but it's true that it would be very expensive and take a lot of math and planning to pull it off. You need someone who is certified by the national tile organizations (can't remember the names), but they need to go beyond that with passion and experience. Someone who enjoys challenging themselves. It would be so cool to see something like that come together, but it'll cost you a pretty penny. Depending on where you are located you might have to entice someone from far away. Hopefully you are in a sophisticated city center or an artistic area.

On my monitor they look like 2 different tile colors they are just wood look tiles so go to a tile store and see what is available. I personally dislike them or any tile all through the house unless you live in the tropics and those don’t even try to look like actual wood floor.
