The color of comments is not in fact a property of the comments, but is set in appearance preferences. The color will only differentiate comments according to comment author, and the only way to get a different author is to open the document in a program registered to a different person.
You'll have to look for a different way to differentiate the comments, or use an entirely different approach.
