Certainly makes it less likely to be a simple surface marking caused by discolored water or newsprint. But something more permeable (like a sharpie marker) could leave marks that may take several sheds to completely fade away. It doesn't look like any scale rot I've ever seen, but it could be some weird fungal issue.

The pictures are too small, and not nearly enough info has been given for us to do anything more than toss out random guesses. I just figured I'd throw out something I hadn't seen anyone else suggest.
