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.
