Yeah, I'd love to see a deeply pigmented(preferably eastern African) actress cast in the role, and yes, bring back the sky blue eyes(cat-slit pupils optional), and the widow's peak hair(I'd love to see a microbraid or loc style for deeper visual complexity) snow white. The salt and pepper looks from X3/DoFP weren't horrible, but I'm tired of the idea she was born with black hair that later changed to white. No. She was born with white hair, period. Her eyebrows and lashes should even be white(makeup team will hate this, but with a dark skinned actress it could look incredible). She's a mutant goddess. She should look different!
X2's soccer mom cut, platinum blonde color, was the height of wrongness!
