Possibly silly question, but why are colors forced to be X11 in fret
diagrams?
When you recolor a NoteHead for instance, you just use the literal color
value:
%%%%
\version "2.20.0"
{
\tweak color #'red b'4 % symbol is invalid, defaults to
black
\tweak color #red b'4 % color value stored in variable
\tweak color #'(0.9 0.5 0.2) b'4 % custom color as an RGB list
\tweak color #(x11-color 'tan) b'4 % looking up X11 color
}
%%%%
You cannot do this with fret diagrams, as the internal logic assumes
colors are X11 names only.
Not being able to specify a literal color feels inconsistent and
arbitrarily restrictive.
