Staff with two lines of F and C cleffs

[fstirpe]

Hi All.
I'm trying to draw a staff with the two cleff lines (F in red and C in yellow).
Does exist a way with Gregorio or with LaTex for doing it?
In attachment you can find a B&W example of what i'm looking for.
I wonder if you could help me.

Thanks and regards.
Fabio.

There is no way for different lines within the same set of staff lines to be different colors within Gregorio. Different scores can have different color lines and it's probably feasible to change the color of the lines between lines within a score, but that's about it.

Of course, LaTeX will allow you to draw arbitrary lines with arbitrary colors (with the right packages), but they won't be Gregorio scores.

Hi Mr. Springuel and thanks for your answer. How Gregorio and/or GregorioTex generate the staff? In your opinion is it possible to slightly work inside the staff generation mechanism to have the two lines-staff with red and yellow? Thanks and regards for your help. Fabio.

The function which generates the lines is \gre@generatelines. If you redefine that function in your document, then you might be able to achieve what you want.
