Very nice.

However, I'd like to write a function that toggles the color value (without
recourse to the customize menu), since it would be useful to highlight the
footnotes from time to time.

After some tests, it is clear I also disliked the underlining.

Put your cursor on the footnote.  Then do

    C-u C-x =

In the resulting buffer, toward the end, you will see something like
this.

Click on the face property (which is `org-footnote').  Click on
"customize this face" link.  Change the face foreground color to
whatever you want.

Or

A fast way to do that would be
    M-x customize-face RET org-footnote RET

You can also try
    M-x customize-group RET org-faces RET
