It's an obsolete snippet that will likely need to be removed when LSR 
moves to 2.26 as the stable version.  This type of functionality is 
directly supported in LilyPond via staff highlights [1].

The source of the error is how colors need to be handled.  Add an 
explicit call to normalize-color:

    (ly:make-stencil (list 'color (normalize-color color)
