Or bright red (think Coca-Cola) but only for accent.
My kitchen's color scheme is similar to yours except for white instead of black appliances (only my microwave is black). I've done blues because a friend gave me a variety of blue-and-white dish towels, and red because red is my favorite color.

what a gorgeous base kitchen you have to start with...I'm sure whatever you decide on will be beautiful! I love that first link that was put in there, wish I had the wall space to do that but our kitchen walls are pretty compact.
I used a sort of muted green on my walls - available at Home Depot, and the color is called Lion. It looks fantastic. I painted my cabinets black and added granite tops. The granite pattern is called Uba Tuba and is green/black/brown. (Disclaimer - I worked for a builder at the time and our granite supplier gave us a significant discount).
For the backsplash, I went simple with 4x4 tumbled travertine tiles.
Now, if I could just do something about the ugly appliances. . .sigh.
