First, take a deep breath. This problem comes up here a few times a month! Step back and look at how the over all color "reads"in your kitchen. The reason why Laurie's looks so good is that it not only blends with the St Cecilla but it also blends with the cream in her cabinets. What color are your cabinets? If your cabinets are white and the counters read more grey, I would try to find a white tile with a grey undertone. Or a very light grey. Can you post your kitchen? It is funny that you mentioned no backsplashes shown with your granite. When I was having difficulty finding a backsplash, I went back to see my inspiration kitchen pictures. (They were white kitchen) Not one had a backsplash! I was so involved in the style and the color of the cabinets, I did not think ahead about the vision of my backsplash. There are a few directions that you can go in, but if you post a picture it is easier for us to help you.

I am in a hurry, so I am going to post a link to my house photos, which include photos of our bianco romano granite with marble subway tile splash. Sorry for making you scroll down but there are a few photos of the kitchen. We are still very happy with our choices and we did our kitchen in 2004. Here is a link that might be useful: Wood cabs/bianco romano granite/ marble subway splash

No "rules" whatsoever. Rule-wise, design is free as the breeze and wide open. There are, however, a number of general looks that people in general tend to find generally pleasing. My personal preference is for counters that blend with the lower cabinets and the walls behind them. Most people, however, choose counters that strongly contrast and form a horizonal line around the kitchen. So, I guess, what most strongly approaches a rule is the need for you to research to determine the look that most pleases you and take that as a starting point. Have fun!

Dark flooring shows dust, etc. In my remodel I am avoiding dark, and finally decided to go with a clear maple. Another consideration is that tile is very hard, and can be tough on your back if spend long hours cooking. I was very intrigued by rubber flooring, which is available in a lot of colors. Its soft, diverse, and quiet.
