For liturgical books, it is often useful to get red staff lines. GregorioTEX offers this possibility. To get red lines, simply call the macro \gresetlinescolor{gregoriocolor}. This will make the lines of all following scores red. To cancel it, call \gresetlinescolor{black}.

contains an error: this should be gresetlinecolor, not gresetlinescolor; that is without 's' in the middle
