Multicolored horses... Great! But why no multicolor chocobos?

Mhrhn, when you say barding, do you mean stables and multiple chocobos? Like a breeding system? I would enjoy that myself.

Barding is the gear you equip to your Grand Company chocobo - it's a collective term for the saddle, harness and bridle it wears. At the moment, the barding is purely cosmetic, but apparently later on SE will be making it that it has actual stats like character equipment.

As for coloured chocobos, at the moment the closest we have to a chocobo of a colour different to the standard yellow is the little Black chocobo chick minion from one of the Veteran Rewards, so lore wise at least, it's entirely possible black chocobos at least may make an appearance later on in the game.

It should also be noted that lore-wise, chocobos in Eorzea have only just come back from the very brink of extinction, just prior to the Calamity a devastating plague called 'chocobo blight' was afflicting chocobos across Aldernard, forcing the Ishgardian stables to quarantine their birds and thus preventing them from providing them to the other city states. This was the in-game lore reason given at the start of 1.0 why players were unable to ride chocobos then.

Only later on did the blight diminish enough that Ishgard decided that the danger had passed and thusly allowed adventurers to ride their birds again (hence why it's a Grand Company that issues you your chocobo and not a regular stable - the chocobo population in Eorzea is still pretty low and hence the birds that can be spared are provided only to organizations who really need it, ala, the Grand Companies.). Maybe the chocobo blight also is responsible for rendering other breeds of chocobos (ala chocobos of different colours) extinct as well. Or maybe I'm just looking too much into this.
