What compatibility are you needing?

I intended \highlightPitches to be a significant upgrade to my earlier 
\highlightOutOfRange, which I would no longer recommend using.

Of course, it is not a drop-in replacement, as there were several 
significant changes in its interface and usage:

%%%%
% original %
\override NoteHead.color = \highlightOutOfRange c' c''

% new %
\highlightPitches outside { c' c'' }
%%%%

Of note, the \override is now encapsulated within the new music 
function; and when specifying multiple pitches, they must be enclosed in 
curly braces.

Yet it is that second change in interface that ultimately permits what 
you had requested:

%%%%
% requested (though invalid) syntax %
instrumentRange = c' c''
\override NoteHead.color = \highlightOutOfRange \instrumentRange

% realized syntax %
instrumentRange = { c' c'' }
\highlightPitches outside \instrumentRange
%%%%

Please let me know if I am overlooking a critical detail in your use 
case where my newer function would not be fit for purpose.
