Have You Ever Colored Your Hair Darker or Redder For Fall?

Going darker or redder, like Scarlett did in January, is the traditional seasonal change to make to your hair. But I don't see as many people doing it as often as magazines suggest. I don't know that I usually think about seasonal propriety when I get my hair done, but maybe I should. What about you? Have you gone redder or darker as the days get shorter? Or is your hair color only dependent on your mood?
