Some of the roman units are not in the traditional red robes. I think they look beautiful regardless, but is it historic?

I heard some one say that nobody truely knows what color the legionnares wore, if this is the case, who made up the red look?

Red is seen as a "godly" color in many civilizations, Chinese come to mind. Did the Romans feel the same way about red?
Most likely their colors were far less saturated than Hollywood has imagined.
"The Passion" gives a more gritty and realistic view on the imperial troops I think. Brownish leather and such.

The Romans certainly didn't have any team color as qwerty says. They had identifying plumes on their helmets though, as well as their "signae" (standards).
Velites were poor - and would probably not bother paying for dyed clothing. I'd expect to see a myriad of colors from one Roman army. With much white, brown and dark red.
