It seems Demi Lovato is still in her blue period. The X Factor judge stepped out for the premiere of Disney's Frozen last night with her freshly colored hair pulled back into a tousled updo. Perhaps it was in spirit on the film, but Demi's hair was a rich, radiant shade of blue, darker and richer than the colors she's tried before. She complemented her azure mane with a neutral makeup palette that featured a shimmering bronze shadow dusted all over her lids. What do you think of Demi's jewel-toned hair?
