I just want character consistency.
As you can obviously see, Tanya has had tan skin in both her iterations, and hopefully she will in MKX as well. I'm sure she will, I doubt they would suddenly turn her pale. As mentioned, though Jade was pale in her MK9 render, she was dark-skinned in-game and that's what matters.
Like Jade, Tanya is Edenian, and most likely both from a region where most people have dark skin, like we have on Earth. What the name of that region is is unknown though. Africa, however, is a place on Earthrealm, and neither of them are from Earthrealm, so no, they can't be African-whatever.
As for what most people prefer when it comes to female skin-colour... that doesn't really matter in this case. Tanya has always been dark-skinned, and so there's no reason to change that. What you prefer is of no importance. Pick another character then. There's no need for racist comments, and they have all been reported and further comments of the same nature will also get reported. So please refrain from making such.
Thanks. ^^
