M-x customize-apropos-faces RET outline

Then expand the faces you are interested in, "Show All Attributes", set
a foreground color, and either C-c C-c (set for session) or C-x C-s
(save in your init file, or custom-file if that's set).

With outline-minor-mode-highlight set to 'override, that should ensure
all outline headings have the same foregrounds, regardless of the major
mode.

If you do not wish to go through Customize, you can probably use
set-face-foreground in your init file.
