This is what I found, but I think the size of the tile is a bit larger. http://www.glasstilestore.com/tao-starlight-p/taostarlight.htm

Here are a couple of pics from google. probably not close to your colors, but maybe it will give you an idea?

If you're gravitating towards a darker/more intense color for the walls, perhaps it's because you're enjoying the play of contrast against your newly white cabinets? Personally, I love the contrast of gray against white (or cream). I also think cabinets can play a dominant role in a kitchen, so just because your walls are darker doesn't mean that your entire kitchen will be. You can always paint again with a lighter gray if you find the one you choose to be too dark in the end. Also, I highly recommend you be patient and put some thought/research into the color of your subway tile grout after you install. There are numerous posts on GW about gray vs white subway tile grout. Personally, I like those that use a light or medium gray that show off the shape of the subway tiles. Grout the color of the tile will lose the shape to an extent and you'll mostly see color. That may be the look you want, but I personally try to avoid rushing a grout color decision.

Pics of my kitchen are in my idea book under "my pics". The cabinets are older, so probably not an inspiration, but I am very happy with my new farmhouse sink, counters and backsplash.
