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,
