scarlet witch’s eyes

i have been trying my hardest not to ask this but her eyes are blue. why? her eyes from what i know are literally never blue in any other context. i have seen them brown and obviously red.

i understand that they choose this for a reason, why would they change something like this? she has a decent amount of cutscenes with her eyes as the focus, feels like its being pointed out at times.

was wondering if anyone knew why or more likely just have ideas.

edit/ theyre blue in x men evolution lol
