Hi,

try:

\version "2.14.1"

#(define (color-at-line-begin g)
  (if (and (ly:item? g)
           (equal? (ly:item-break-dir g) RIGHT))
      (ly:grob-set-property! g 'color red)))

\relative g' {
        \repeat volta 2 { a b c d }
        \break
        \once\override Staff.BarLine #'after-line-breaking =
#color-at-line-begin
        \repeat volta 2 { d c b a }
} 

Greetings,
  Harm
