If you want to avoid switching to LilyPond, you can of course replace
#{ #@... #} with (make-simultaneous-music ...).
Or to be completely nitpicky, (make-simultaneous-music (set-origin!...))
so that point-and-click/error information of the overrides will be
correct. Which is sort of pointless for this particular application
since overrides are no clickable entities and the only conceivable error
is when `color' is not a color and then the music function would not
have accepted it in the first place.
