I just thought of something that might possibly be relevant (but probably isn't) while making a post in another thread:
It seems as though Firaxis are using the same colour schemes for Civs as they did in Civ V, except for Egypt which for some reason they have reversed (it's now Purple/Gold, like Rome's Civ V colours). Quite why they did this, I don't know. Why might it be relevant? Because Rome would now need a new colour scheme, and I can't see them using Egypt's Yellow/Purple. If I had to guess they would probably use Red/Gold, as those were the colours used on Roman Vexillums (military standards/banners). Who used Red/Gold in Civ V? Persia.
This makes me wonder whether perhaps that colour scheme was no longer being used in VI, allowing Rome to claim it. If those colours weren't being used then perhaps Persia is not in the base game, meaning C5 cannot be a Persian leader.
Now - I'm not suggesting that this is a sound theory (because it really, really isn't) but seeing as we have so little to go on at the moment I just thought I'd suggest it. Also, I'm aware that it relies on several major assumptions. Firstly that Rome will have a Red/Gold colour scheme this time round (we can't be sure of that until they get properly revealed). Also it assumes that Firaxis follows any kind of particular, consistant logic behind their civilization colour choices at all, which they might not (though I would guess they'd try to avoid giving civs similar colour schemes where possible). I can't really explain why Egypt is Purple/Gold now either, unless there were too many civs using yellow as their main colour in the start lineup (Russia + one of the new civs perhaps?).
Anyway, just a crazy idea that may be of interest. Or not. (I blame this all on a combination of extreme boredom and tiredness.)
I thought about that too, and I hope red and gold are indeed the new Roman colours. Persia, if Achaemenid, should be represented in the game by cyan and red, like this symbol.
