Is it black or is it blue? That's the debate stirring on social media over the first lady's shiny leather trench coat that she wore to the College Football Championship Game in New Orleans. Some say it looked black as she walked across the white house lawn on her way to the game. Under the bright lights of the Superdome, others claim it looked dark blue. According to the designer, Scanlan Theodore, the $2,000 coat is black.
