For example, something like Demacia silver, gold and blue for people like 
or 
, or for inverse, Noxus black and red for someone like 
or 
. Zaun colors for piltover champs, like a more rustic and "battlecast" styled full metal 
. Chromas bring a lot of potential for cool stuff like this, and I'm really excited for what Riot can make up from them.
Here's a quick little ditty I dun up for a Solari Diana. I think it could be done.
Zac should get a purple chroma and have it be the price of a real skin.
Blood moon diana should be made
Those seem a bit more than what the chromas are aimed for, which is not redoing the fantasy of a champ (that's what a skin is for)
That's a pretty nice job on the Diana re-skin, although it looks a little more Shuriman than Solari
Noxus Poppy might as well be a chroma ;*(
eeeew
Zac isnt even worth a chroma skin update!? Riot you are cruel to Zac fans and players.
I don't really have an opinion either way on the Chromas, but that's a really good model edit for Diana there.
