Thanks for the code -- it let me try it.
I found that my previous reply actually didn't work. Although the
ChordSquare does accept the whiteout property, it actually doesn't
draw the whiteout box correctly. I believe this is a bug in the
ChordSquare code.
But you can change the color of the chord names and the repeats:
%%%% Code begins
\version "2.24"
\score {
\new ChordGrid \chordmode
{
\override GridChordName.Parentheses.font-size = #2
%\set chordRootNamer = #chordNamer % substitution du nomage
des accords
% \set chordNameExceptions = #chJazz % substitution de
l'affichage des extensions
\override GridChordName.font-size = #3
\override GridChordName.font-name = #'"lilyjazzchord"
\set chordChanges = ##t
\set noChordSymbol = "—"
{
%\override ChordGrid.ChordSquare.whiteout = ##t
% \override ChordGrid.ChordSquare.whiteout-color = #(rgb-color 1 0 0)
\override GridChordName.color = #(rgb-color 1 0 0)
\override PercentRepeat.color = #(rgb-color 1 0 0)
\repeat percent 2 {d1:6.9}
\override GridChordName.color = #(rgb-color 0 1 0)
\override PercentRepeat.color = #(rgb-color 0 1 0)
\repeat percent 2 {e:9}
\override GridChordName.color = #(rgb-color 0 0 1)
e:m9
\override GridChordName.color = #(rgb-color 0.5 .5 0)
a:7.13
\override GridChordName.color = #(rgb-color 0 0.5 0.5)
\override PercentRepeat.color = #(rgb-color 0 0.5 0.5)
\repeat percent 2 {d1:6.9}
\break
}
}
\layout
{
\context
{
\ChordGrid
slashChordSeparator = % is only a dividing line;
#(make-with-dimensions-markup (cons 0 0) (cons 0 0) ;; displaces nothing
(make-translate-markup (cons -1
-1.5) ;; just clear of root-stuff base
(make-rotate-markup -45 "/"))) % roughly perp to bass/root axis
chordNoteNamer = #(lambda (p l?)
(make-lower-markup 2.0 ;; not too cramped
but still belonging graphically
(make-small-markup ;; as
qualifier is subordinate to root name
(note-name->markup p l?))))
}
}
}
HTH,
Carl
P.S. The code you sent was missing the definitions of chordNamer and
chJazz, so I had to comment out those lines.
