Hans will probably answer you better, but in
http://source.contextgarden.net/metafun.mp
there are files with metafun macros included which may set their own
colors. See those files.

I doubt that any definitions can be removed without breaking anything
(otherwise they wouldn't be there), but I agree that MPinclusions
could/should be included AFTER metafun macros if they're not (I didn't
check).
