God, I was positive it was gonna be the color of the snow on Hoth this time around.

After watching the workprint on my HDTV this was actually the only thing I was unsure about. I thought Hoth was going to be more blue (which I've gotten used to) and so many discussions had come to the conclusion that it was originally blue much of the time.

The thing that really stood out for me was much of the time on Hoth it seemed to be closer to a shade of purple. I'm surprised I'm the only one whose noticed this.
