 The beautiful model/actress Lily Cole traded her signature red for dark brown hair color. With her pale skin and light blue eyes she reminds me of Snow White. With a red lipstick it would be spot-on. She looks pretty and going dark is totally "in" this season.
 But still - her almost fire-red hair looked so gorgeous on her.

What do you think? Is Lily's dark hair a makeover or a makeunder?
