If the same region of text is highlighted both by the major mode and by outline-minor-mode, the resulting colors will be different from what you might expect, because Emacs will merge the two faces. > For instance if I make my own `outline-regexp` how > can it conflict with the major made? By highlighting the same parts of the buffer text. You basically tell Emacs to use two different faces for the same text, so the result will be the merge of the two faces.
