Eh, personally I'm not too fond of most of Bayonetta's colour swaps. For her Bayonetta 2 outfit, the default and the silver one just look too similar. I'm not too crazy about the orange one. In mine opinion, black with colour--especially bright colour--just makes the colour look cheap and the black dull. [Shrugs] Then again, I'm willing to bet it's based off of Loki, since Loki wore orange. I do like the Jeanne costume, though.
As for her Bayonetta 1 outfits, I think they could have picked better choices than the traditional red, green, and blue. The red one looks okay, since it matches her guns. But the green and blue, in mine opinion, just don't go well with that particular design. The green, in mine opinion, doesn't complement her guns--same with the blue. Again, in mine opinion, black with colour makes the colour look cheap and the black boring.
For the Bayonetta 1 costume, I would have done another Jeanne re-colour, a white colour, and kept the red. [Shrugs] But oh well. What's done is done.
I think I'll just stick with the default Bayonetta 2 costume, just how I stick with the default male Robin costume. [Shrugs] Though I might change mine mind later and stick with the default Bayonetta 1 costume, since I really like the chignon; it's very unique and exotic-looking.
