I think that symbol-list-or-symbol? is what you need:

\version "2.19.8"

ed = #(define-music-function (parser location grob mus)
        (symbol-list-or-symbol? ly:music?)
        #{ \override $grob . color = #(x11-color 'grey40)
           $mus
           \revert $grob . color #})


\relative { \ed NoteHead c' \ed Staff.Accidental { cis dis } es }

best,
