This is how to do it:
\relative c'' {
\override Score.BarNumber #'break-visibility = #'#(#f #t #t)
\override Score.BarNumber #'stencil =
#(lambda (grob)
(let* ((stil (ly:text-interface::print grob))
(text (ly:grob-property grob 'text))
(nmbr (string->number (markup->string text))))
(if (= (remainder nmbr 5) 0)
(ly:grob-set-property! grob 'color red)
(ly:grob-set-property! grob 'color black))
stil))
\repeat unfold 41 { c1 }
}
Best,
David
