About the alt colors, it will be between Blue B1, B1 and B2.
As someone who discovered Bayonetta on Xbox360, I simply prefer the old design, although B2 have a great design too!
B1 red, blue and green aren't creative. It's not Melee! But the blue and Red does have a good shade. We can easily tell them appart, compared to a certain swordman
B2 colors... I'm not really fan of them. The yellow one is weird to me, and the silver one, it's kind a shame that she retains her black "shawl" (make sense as it's her hair). The Jeanne one is cool, but Bayo with White hair is weird, that's probably because I really like Jeanne!
