The first lady blamed "lighting" for the differences between two photographs taken of President Barack Obama one day last month. His hair looks darker in one photo than the other.
Mrs. Obama told NBC's "Today" show Wednesday that her husband "is pretty gray" and might have started dyeing his hair 10 years ago" if he had known he would become president.
She also said Obama "cares very little about his appearance." She said wishes the president would try "a different color suit," and she and her daughters "cheer when he puts on a bright-colored shirt."
