Just a little ceramic information to share as a potter. Vitrified simply means the clay has become glass like by being fired to its proper maturing temperature. Usually ceramic tile means it is a lower temperature clay like earthenware or terra cotta. Porcelain is fired to the highest temperature and is more vitrified if you will. This usually means it is less porous to to absorb water and harder. Low fired ceramics with glazes much darker or lighter than the clay body will show chips easier. Rectified has to do with making the edges precise enough to fit smoothly together for less grout lines. So porcelain cost more to produce but it is more sturdy. All clay tiles should be vitrified.

These are a tough find! I do know that they get a lot of furnishing items form Mitchell Gold http://www.mgbwhome.com/. I could not find the lighting on there, but, you may want to occasionally check their website. They are going to set up a Good Wife furnishing collections soon :) sorry I couldn't help!

There is a specialty lighting store near me that I am going to soon with photos to work on lighting at my house. I will show them your photo and see if they have an idea. Probably won't be till Fri or Sat but will get back to you.

A soft, warm grey shade would look lovely, and can be as dark or light as you want. A warmer shade will work with the brown stained wood floor, and the grey will complement the black granite. You could have an undertone of green, blue or tan if you didn't want a pure grey. And it would look nice with any silver metal hardware, either polished or satin/brushed, so you could choose pewter, chrome or nickel. It would still work with white trim too.
