Generally, I wear matching leathers, or as close to matching as possible. I do this with both highland as well as regular dress. Nonetheless, I think you can wear what you describe without any problem. Perhaps, later you can find a nice brown sporran to match.
I also have a nice pair of brown brogues, and I am searching for a complimentary sporran.
