Have you tried tweaking outline-minor-mode-highlight (introduced in
Emacs 28, i.e. on the master branch)?  Setting it to 'override (and
reloading outline-minor-mode) does exactly what you would like, AFAICT
from reading the docstring, and trying it out.

Yes, I am forced to use 'override.  It is weird because if I set my own outline highlight pattern

for a particular major-mode, I really want to override, otherwise I would use something else.

Wouldn't customizing outline-[1-8] faces (plus setting

outline-minor-mode-highlight to 'override) allow exactly that?

How does that work? The code uses only colours from inherited faces. There is no way to set the

colour directly in hex.
