OK, but the requirements are still not clear.  First, what do you mean
by "remove a highlight from a buffer", and what "change in its
appearance" did you have in mind?  And second, what if the same buffer
is displayed in more than one window?  Finally, why the differences in
the mode-line appearance are not already what you want?
