OT: The Yellow and Blue?

My wife and I had an outstanding visit to Michigan recently, and we made our way through the campus for dinner and whatnot. I was looking to pick up some things and stopped into the MDen and Moe's, when my wife made the comment, "Do you notice how there's no maize any more? It's yellow."

And I looked around. For the most part, she's right. It never occurred to me until that point.
