I only saw one pic and I liked it. I wanted to do something somewhat similar, yet with more grays, so we are kitchen sisters from another mister! Honestly, I found the tile and grout situation the MOST agonizing of the entire process. It tormented me night and day. I did countless sample boards and still was not sure. Installed, grouted, and sealed the tile myself in the last week or two and I can finally say that I am happy about my choices. Next time, I think I will start with a tile that I love and make all my other choices at that point. Once you get more stuff in your kitchen and get to use it, you will really come to appreciate it. I am sending you falling-in-love sugar dust for you and your tiles, because they really look great!

As an example here's a link to some of the color choices Leviton offers in their Renu line: http://www.leviton.com/OA_HTML/SectionDisplay.jsp?section=63008&minisite=10251&itemsPerPage=All You could go with a gray or brown plastic for everything or try to find a plastic outlet that best matches an oil rubbed bronze face plate. Just wanted to let you know there are choices other than black that I think would really look great in your kitchen.

Beautiful!

I am obsessed with large format subway tiles (4x16). I'd try to match the white for the tile, and maybe pull one of the lighter gray colors from Brittanicca to be the grout color. Depending on your floor maybe you could pull one of the lighter colors as your paint color- this way you'll have some contrast without taking away from the Cambria! I'm attaching a photo of 4x16 with a contrasting grout!
