On the red carpet, blue was the color of choice for many stars.
Nyong'o was dressed in a striking sky-blue Prada gown. Liza Minnelli and best actress nominee Amy Adams ("American Hustle") also were in shades of blue.
Jennifer Lawrence was an exception: She was in a striking red dress.
But for "12 Years" actress Alfre Woodard, very little of the glitter mattered.
Asked by CNN's Piers Morgan what she was wearing, Woodard laughingly turned the question back toward the work that got all the nominees to the red carpet in the first place.
"I hope I'm wearing my talent tonight," she said.
