Costume

A palette swap is a feature in Super Smash Flash 2 that allows characters to swap between different costumes of different colors, with the main purpose of distinguishing players that are using the same character, although they can be used as personal preference too. This is one of the many features carried over Super Smash Bros. games to Super Smash Flash 2 and, as such, was absent from the original Super Smash Flash.

It was first presented in demo v0.4a as simple tints ranging from red, green and blue, solely for the purpose of Team Battles. This remained the same until v0.9a which was the first one to incorporate actual color changes, replacing the old tints. In Free for All, most characters have 6 colors to choose from, with some having as many as 7 and others having only 5. In Team Battles however, characters can only change color by changing teams (which only supports 3 colors: red, green and blue). If team members choose the same characters, the second will have a lighter tint applied to their character; a third member will have a darker tint. In Online mode two players can select the same tint with no way to tell apart from each other.
