[Accessibility?] Allow custom professional/out of range color noteheads

Your idea

Add a way to change the notehead color of both the out of range notes and the ones outside of the "amateur" range.

Problem to be solved

Currently, these noteheads are green for professional and red for unplayable.

That does make sense unless you're red/green colorblind like me and a bunch of people, who will either struggle differentiating them or just will see both as the same color.

Prior art

No response

Additional context

Other colors are able to be changed in the "Advanced" tab in settings so I don't see why this shouldn't happen.

I also think this was possible in MS3.x but I'd really have to check.
