IMHO you probably would rather have this a grob property of grob bar-line,
maybe something like

\notes {
  \property Score.BarLine \set #'repeat-bar-style = #'vienna
  \property Score.BarLine \set #'repeat-bar-color = #'blue
}

or

\paper {
  \translator {
    \ScoreContext
    BarLine \set #'repeat-bar-style = #'vienna
    BarLine \set #'repeat-bar-color = #'blue
  }
}

Color support is also on my wish list (a couple of months ago, I wrote a
mail with a dozen of situations where you want to use colors), but I guess
this is a major project: For example, you have to consider the order in
which the grobs are output.  If a blue repeat bar crosses black staff
lines, you probably want to have the staff lines be typeset *after* the
repeat bar (i.e. black staff lines on blue repeat bar).

The vienna style bar lines should not be that difficult to implement
(if you like, look at lily/bar-line.cc, function
Bar_line::compound_barline, to see for how it currently works).
