[jmsl] change color of Note / acceidental / ledger lines / etc.?

[jmsl at music.columbia.edu]

Hi Jason

I don't see an easy way to do this. 
But adding setColor() to various Score components would be very easy for 
me to do. 
What granularity would be helpful? Could these be a bunch of static 
methods in Score, such as:
Score.setNoteHeadColor(Color c);
Score.setBeamColor(Color c);
Score.setNoteStemColor(Color c);
Score.setAccidentalColor(Color c);
Score.setBarColor(Color c);
Score.setStaffColor(Color c);   // also affects ledger lines
Score.setBackgroundColor(Color c);
Score.setTextColor(Color c);
...
what else?

Thanks
Nick Didkovsky
