It is dated now but green ink was the thing for a while since it couldn’t be scanned. I would sometimes mark up a document that way if I wanted to just have a scratch copy for my own notes. Then when I was sure I could use red ink, scan it, and only the red was on the document.
Just use blue ink, it’ll be fine.
