Shields?

Its not really that there isn't evidence. There's friezes depicting roman soldiers. The problem is that no one knows how exactly to intepret it. http://www.larp.com/legioxx/tcolor.html has some(yes its a site for larpers but it links to pictures of friezes). There's ones depicting, red, blue, yellow, white, etc. No one even knows if there was a required tunic color. If we went back in time and asked someone, they might just say 'we wear the colors we like."

However at the end of the day, whether there was or wasn't a required color for tunics, the real 'uniform' of the later legionaires come from similarity of equipment.
