Color Elements of the Score

Hello,

I found a Plugin Version that let's me specify the color of notes (including stems and beams)

I would like to be able to color:
- Staff lines
- Notes
- Rests
- Bar Lines (Vertical Lines)
- Lyrics
So all of this categories in different colors.

Can I do this by writing a plugin or must this be done on a lower level?
Has anyone a plugin to do things like that?

I'm grateful for every help
