At first glance, it might appear like each character found within the game only comes with their usual color skin that most fans are use to. However, the truth is that each character actually have three additional colored skins that can be unlocked. In order to obtain each character's Alternate Skins, you must play Arcade Mode with said given character. If you'd like to unlock all four Character Skins for each fighter, you'll have to complete Arcade Mode multiple times with each.
