Colour of a Draco

[Nathan Ross]

With one per cohort I assume that every soldier knew where to look, and they would never 'get lost in a sea of dracones'.

For the individual soldiers, I'm sure, yes, they would just have glanced towards their nearest draconarius... But for the commanding officers, looking out over a battle line with every 500 men (or whatever a 'cohort' might have meant by that era!) having an identical purple draco, it would indeed have looked confusing, and hard to distinguish one unit from another... Unless it was just a way of assessing losses: count the number of dracones still in the air!

I suppose it depends who these various signa were for...

Thanks for the red/purple reminder too, btw!
