But again, the Developers at 2K Australia did NOT stick to that concept art, and changed the skin tone from what it was on the concept art! For frak’s sake, just look at her actual, on-screen appearance IN-GAME!
And again, since AT LEAST Borderlands 2, the Devs have been very open and honest about the fact that many of the Vault Hunters were inspired by other popular fictional characters out there in Pop Culture. Axton is Duke from G.I. Joe: A Real American Hero, ZER0 was inspired by pretty much every popular ninja in pop culture from the last 35-40 years, from Snake-Eyes (again, G.I. Joe: ARAH) to the cyber ninja in the Metal Gear Solid games, and beyond! And Aurelia was clearly inspired by Killer Frost, from the ice powers she wields as a Player Character, down to her tendency to wear outfits that are mostly shades of blue, and even her choker has an icy star symbol, similar to the symbol Killer Frost usually wears. About the only thing missing is skin that’s actually white or pale blue, which is how Killer Frost most often looks in the comics, and even in most of her video game appearances:
Now, in the TV show, her skin tone change isn’t as extreme, and it looks more realistic, but it is still pale, because that reads as icy and cold:
So, you just have to excuse 2K Australia for changing the skin tone to better match the character that inspired Aurelia.
