\override NoteHead.color = red

actually lowers the barrier immensely compared with

\override NoteHead #'color = #red
red and #red are completely different Scheme entities.

Yes indeed (I suspect red gets parsed to #'red, no?). I never took the time to find out what's happening there behind the scenes, but as a frequent user of the colors "darkred" and "darkgreen", I'm a bit nervous about:

lukas@Aquarium:~/git/lilypond/scm(master)$ git grep darkred
color.scm:    (darkred 0.54509803921568623 0 0)
output-lib.scm:(define-public darkred     '(0.5 0.0 0.0))

lukas@Aquarium:~/git/lilypond/scm(master)$ git grep darkgreen
color.scm:    (darkgreen 0 0.39215686274509803 0)
output-lib.scm:(define-public darkgreen   '(0.0 0.5 0.0))

@everyone: Is this as it should be?
