Palette Swap (Super Smash Bros. Brawl)

Super Smash Bros. Brawl changed the idea with color changes just a bit. While Melee added a few extra outfits to some characters, Brawl promises six colors each.

However, there are exceptions. All the playable characters of the Pokémon universe (Pikachu, Jigglypuff, Pokémon Trainer and Lucario), as well as Sonic, have less than six. The other exception is that Wario has two outfits, each with multiple color choices, effectively doubling his alternate costume choices. The costumes can be cycled by clicking on the character (any controller), pressing A/B (Wii Remote), pressing 1/2 (Wii Remote w/ Nunchuck), or pressing X/Y (Classic, GameCube).

Color Blindness

A few characters (namely, Lucario and Sonic) have sets of costume changes that can be difficult to distinguish from each other in a match. As such, tournaments have a rule stating that in a doubles match, a partly colorblind Lucario or Sonic player may request to be given the blue team. In some cases, texture hacks are used to make the color difference more obvious.

Samus

Orange	O	Based on the Varia Suit from Metroid: Zero Mission. Brawl is the only installment in the Super Smash Bros. series where Samus cannot wear her default color (despite wearing it in both Smash 64 and Melee --the first two installments in the series). That's because all the normal Samus alternate colors are paired with the Zero Suit Samus ones. For the default color (in both Samus and Zero Suit Samus), the normal Samus is orange (the color she wears if she is using the default costume) and the Zero Suit Samus is light blue. The reason why the pink one is used instead for the red team color is because the developers of the Smash series needed to give Samus an alternate color relating to red in order to have both of the characters use red for team battles.

Pink	P	Similar to the appearance of the Varia Suit when missiles are selected in the original NES Metroid game.
