Last night in Los Angeles at the premiere of The Ugly Truth, Katherine Heigl wowed the red carpet with dark auburn hair. Depending on the light and the angle of the cameras, the shade varies between red and chestnut brown, but it's certainly is a drastic change from her usual platinum look. The only other time I've see Katherine head over to the dark side was for her role in 27 Dresses. Out of these three colours, which do you like the best?
