Well, I wasn't aware we create a TieColumn-grob even for stand-alone Ties.
Then you probably should restrict it to occarabces of more than one
Tie at a time. Leading to:

hint =
 \override TieColumn.before-line-breaking =
   #(lambda (grob)
      (let ((ties (ly:grob-array->list (ly:grob-object grob 'ties))))
      (if (> (length ties) 1)
          (for-each
            (lambda (clr tie)
              (ly:grob-set-nested-property! tie '(details skyline-padding) 5)
              (ly:grob-set-property! tie 'color clr))
            (circular-list red green)
            ties))))

\relative c' {
   \hint
   <c e g c e>4~
   <c e g c e>
   <c'>8~ <c>4.
}
