her maskless one is still purple...which should've been blue and even if it's not blue the MKDA primary should certainly be blue, it's an apperance trade mark of the character. lets put sub-zero in brown and scorpion in pink. but yeah maybe this is a sign that you will be able to play with characters in their primary and alt in addition to the P2 colors when someone picks the same outfit. cause i think thats kitana's MKDA P2 alt for the primary.
i'm thinking the if you get them in the same outfit for the primary P1 it will be the original blue and for the P2 primary it will be the purple in the video. for the alt it's purple for P1 but i have no idea what the P2 alt from MKDA was.
