I actually love red hair, but Jason's hair is a weird shade of red, which I personally find hideous.
Also, I don't like the unfortunate implications of making the "black sheep" of the family a redhead. I'm not sure if gingerphobia exist outside of Italy, but here it used to be extremely bad... Thankfully it doesn't exist anymore now, but ever since I read Verga's rosso Malpelo in high school, red hair as a specific "villain trait" always makes me uncomfortable.
As for the white fringe, I find it really fugly, both on Rogue's hair and on Jason's. Although I admit that's a pretty unpopular opinion, apparently a lot of people like white fringes.
