And yes, I use a backward tick here. The forward tick will not
cooperate with the comma later.
I'm not sure to clearly understand
A little background info: The ` and , are abbreviations, spelt out the
above example reads \override #(quasiquote (color . (unquote red))).
Quoting (i.e. '()) means that an expression is not evaluated;
quasi-quoting means that an expression is not evaluated except for those
parts which are unquoted explicitly. #red needs to be evaluated to a
color, so you need to unquote it, and use a quasi-quotation instead of a
quotation.
