All of the components of the robe are two-sided red/black. I can put him together any way you'd like; mostly black, mostly red, a mix of both.
It seems to me the film robes were double-sided so that as they would flow and move the color ratio would change a bit for effect. But yeah, it seemed mostly black. The red side of the panels were seen alot but they mostly showed up as border trim on the black.
