I guess her skin in MKX mobile is rather white, that's why the threadstarter is worried. Her face also looks very Asian there. Well, they actually keep changing Kitana's and Jade's apperances in different games and movies a bit too much, they are not consistent.
Eh, I blame both the power of the average mobile device and the people who created the textures for the mobile "port". Proper shading is virtually nonexistent in MK Mobile, probably because mobile devices lack the power of . For comparison, modern games run under the power of a PC game with a high-end video card versus a low-end video card differ greatly in graphic quality and, with a low-end video card, lighting and shadows suffer the most, so a lot of things that would look brown in the proper lighting look more beige.
In all honesty, having just looked at screenshots of MK Mobile's Jade versus MK9's jade, the skin tones are very similar. The same goes for her skin color in MK Armageddon, but she appears to have more a tanned look or that of a Middle Easterner or someone of Spanish descent, which are the first pair of nationalities that come to mind as the closest comparison to the skin tone of characters like Tanya and MKII/UMK3 Jade.
I dunno, maybe living in the gloomy realm of Outworld under Shao Kahn's rule for hundreds of years led to a more European skin tone and Midway/NRS decided that her skin color should reflect that. Kitana's pigmentation has been consistently European and maybe that's because she was raised by Shao Kahn and has lived her entire life in Outworld. Who knows? Everything can be explained away so long as you're not looking to create an issue out of nothing, heh.
By the way, the movies are so not a part of the official MK storyline, so the appearances of the characters featured in them aren't even relevant.
