Coda/Segno sign color override not working: LiliyPond 2.24.0

[Laurie Savage]

Hi,

I put this in my layout block
\context {
     \Score
     \override CodaMark.color = #red
     \override SegnoMark.color = #red
     \override SectionLabel.color = #red
     \override SectionLabel.font-size = #3
     \override RehearsalMark.font-size = #3
     \override RehearsalMark.color = #red
   }

The result is large red rehearsal marks and large red section labels 
but black segno and coda signs. I looked through the internals 
documentation  (thanks to Michael Werner for your help there).
