You keep saying that, but you look at the duration of the causing event
for noteheads in your example anyway, and of course one can do that with
stems/flags/dots.

colorizator =
#(lambda (grob)
  (define bla (vector red green blue cyan yellow magenta black))
  (vector-ref bla (ly:duration-log
                   (ly:event-property (event-cause grob) 'duration))))

\layout {
  \context {
    \Voice
    \override NoteHead.color = #colorizator
    \override Stem.color = #colorizator
    \override Dots.color = #colorizator
  }
}

\fixed c' {
  \new Staff {
    a4. b'16 c' a8 a'2 g'2. f'4
  }
}
