Reenactment Legion Uniformity vs Variety

[Decimus Claudius Drusus]

Army's today and for a few centuries recent have seen the benefit and perhaps need of having a somewhat uniformed troops. Are we going to flat say the Romans did not consider this, perhaps not in the tunic color alone, but it some way?

Probably not, since we do not see what we would consider uniformed armies until the 16th/17th centuries.

I wont argue the point, since there is no way to know and i could be very very wrong, i just have a hard time believing that such a professional army, that could be considered in ways more advanced than its medieval successors, did not value in some way uniformity, apart of the scutum design, if there was indeed uniformity in that.
