Colored accidentals again

Dear George, do you think it would be a good idea to attribute colors to prime limits? I am assuming that 3-limit intervals could be expressed by black accidentals, 5-limit, red, 7-limit, green, 11-limit, blue... etc..

Cordially,
Ozan

If this were some sort of spectral notation and the F# occurred in
different colors, say black and red, we would quite naturally call
them "black F-sharp" and "red F-sharp" rather than "F-sharp black",
etc. Then what's wrong with saying "comma-up F-sharp" or "5-up F-
sharp", if it were written that way? The only reason we haven't
already been doing that is that we haven't been writing them that
way, and the only reason we haven't been writing them that way is
that we haven't had a good enough reason to do that -- but now we
do. Sagittal is still very new, and it's not too late to think
through these possibilities.

I've previously suggested on a couple of occasions something like
this for use in diagrams:

1 - black (foreground) or white (background)
3 - red
5 - orange
7 - brown (foreground) or yellow (background)
9 - green (odd limit)
11 - cyan
13 - blue
15 - indigo (odd limit)
17 - violet
primes >17 - magenta
7, 11, or 13-limit odds >15 - gray
