Using the same idea as the example you mentioned (http://lilypond.org/doc/v2.11/Documentation/user/lilypond-learning/Advanced-tweaks-with-Scheme) you can base the color on the pitch: #(define (color-notehead grob) (pitch-to-color (ly:event-property (ly:grob-property grob 'cause) 'pitch))) Now you'd just have to figure out how to implement the pitch-to-color function. For example this colors all the flat notes blue: #(define (pitch-to-color pitch) (if (eqv? (ly:pitch-alteration pitch) -1/2) (x11-color 'blue))) You might want to get a little fancy to make sure enharmonic spellings of the same pitch are the same color, but for most cases that shouldn't be a problem. -----Jay _______________________________________________ lilypond-user mailing list lilypond-user@gnu.org http://lists.gnu.org/mailman/listinfo/lilypond-user
