Default huh.
I don't want to read too much into the wording but maybe you unlock non-default colours through the gallery mode.
I do want to hear about the modes in the game. I feel like Capcom is promoting this game in all the wrong ways. Where are the streams showing stuff? Since this game was announced it has been info dump, go dark, info dump, go dark. They don't have a real ad campaign so they gotta find ways to keep this game in the news cycle in a positive way.
