Uhm, I might be still not getting the 2.18.2 compatibility, as this
is what I get:

  warning: type check for `color' failed; value `#<Prob: Music C++: 
Music((origin . #<location  (position unknown)>) (void . #t))((name .  Music) 
(types general-music)) > ' must be of type `color'

When using:

  altoRange = \override NoteHead.color = \highlightPitches outside 
\altoDesignedWrittenRange

Top lines of the highlightPitches are:

  highlightPitches = #(define-music-function
    (parser location color method music)
    ((color? red) symbol? ly:music?)

--strk;
