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.

HTH, Simon
