conditional formatting by note name (again)

[Damian leGassick]

hi all

still no joy with this

for composition worksheets it would be great if i could, for example,  
make all  b-flats and c-sharps red, or have it so that only the notes  
of the E-pentatonic scale have white-note-heads in a chromatically  
embellished piece. i'd like to do this with conditional formatting  
rather than in-line.

i've seen examples on LSR which have some conditional formatting eg.  
based on staff-line position but i can't make the leap to note-name  
(including enharmonic) conditionals.
