Wow...did you even read my post? I'm saying that there can be more than one gene that dictates the color and structure of your hair so its plausible that a change in her hair color can be a result of her mutation. Meaning that hair color is not natural even though the color itself IS a natural hair color (although that natural hair color could be found on a gene locus where it is not considered abnormal.) So no, given that Jean Grey's mutation didn't alter her physical appearance, I don't see why it would change color. Anyways this body suit crap is NOT good. The makeup for mystique was a lot worse than the X1-X3 makeup as is.
