I have a group of borders that make up a small map. Ideally I'd like to be able to bind the border's background property to a property in a custom list and when that property changes it changes the background.

Everything I've read on binding is based on collections and lists -can't I set it simply (and literally) based on the value of a string variable? string color = "red" color = "#FF0000" ...
