Question: Change text color

Hey, just stumbled over this and it looks great! Wondering if one can change the color of the text easily. As far as I understood the configuration of a class like `{foo}` is applied to the shape. Could there be something like `{text:foo}` to be able to set color for the text?

Thanks a ton and feel free to close if not a good question (or I was simply to blind to figure things out!).
