Have you customized the outline-minor-mode-highlight variable? Have
you tried each of its possible values? After changing the variable,
did you re-activate outline-minor-mode?

(Also, what you’re trying to do is misguided, and if you’re doing that
as a library as you’ve hinted in other messages, then you’re harming
your users. For one thing, your modified patterns are suitable only
for languages that treat a semicolon as a comment starter, such as
Lisp; if applied indiscriminately to other languages, users will not
be able to add headings without breaking their language’s syntax.)

(Also, when you think of a possible improvement to a question that
you’ve asked earlier but that hadn’t received a reply, you should post
your improvement as a reply to that past question, not as a new
separate thread. That helps people review all the things you’ve said
in previous versions of the question.)
