Yeah, I just watched that scene. It's very dark, which makes it look almost black depending on the lighting, and there's that one shot (backlit) that you can see the color stronger, it looks more maroon in that shot. But overall, it's a very dark purple/maroon. The scarf/shawl she had at the beginning of the conversation was a much lighter shade.
My TV is badly in need of... well, let's be honest, a new TV. As I was watching that scene, I kept thinking how washed out the blacks looked, and I'm pretty sure it's just the poor black levels on my TV.. I've been spending more time on my computer than the big-screen lately, and my computer monitor is much newer and much darker blacks.
