The visual difference between a new comment and an old comment should be greater than the difference between two old comments.
How about using two pastel colors for the old comments… and using the white background for the new comments?
It would also be nice to have e.g. a small green “NEW” text in the corner of new comments, so I can quickly find a few new comments in a long discussion by using the “Find Next” functionality of my browser. (Because I don’t have a functionality to search a comment based on its background color.)

If you’re going to do this at all, it should be a more-likely-unique string (eg ”!new!” rather than “NEW”).
