I agree. Brogues appear to be the most versatile. I'm assuming shoes, sporran, and belt (if no vest) should match black or brown?

The leather in your sporran or belt needn't match the leather on your shoes. Black brogues with a brown sporran are worn by a lot of people, including Prince Philip and Prince Charles.

Of course, if you're hanging around with a bunch of people who don't know kilt traditions, they might wonder why your leathers don't match. It wouldn't hurt to wear a black sporran with black brogues, or a brown sporran with brown brogues just to appease the American sense of matchy-matchy.
