Alternate costume (SSBM)
Super Smash Bros. Melee added additional alternate costume options to characters by using the X and Y buttons to cycle through the available list instead of using four C buttons to pick a specific color; this removes the limit as to how many are selectable, so there are no longer any costumes exclusive to Team Battles or computer opponents. As a result, many characters now have five different color schemes, with some having as many as six, though some still only have four.
When selecting characters in Tournament Mode, instead of displaying the character's colored image of the chosen costume, the character's name is given a tint and a colored bar is displayed in the player list. This color is usually an intuitive indicator of which costume has been chosen (with no color denoting default), but there are some that are slightly unusual (such as Luigi and Peach's white costumes that are denoted by a grey).
In Team Battle, if members of the same team use the same character, the second player would have a lighter tint applied to their character. A third player uses a darker tint. If a fourth player is forcibly added to a team with the Name Entry glitch, then the fourth character will be completely black; the game's data suggests that a fifth player, if possible, would be completely grey. A sixth player would be completely pink. A seventh player and afterward, would crash the game, additionally it is not possible to view the completely pink character unless additional Action Replay codes are used.
Strangely enough, alternate costumes can affect gameplay, such as Captain Falcon's model changing sizes depending on the costume.
As can be seen in the image, the Ice Climbers' orange and red costumes will place Nana in the lead, making Popo follow.
Notably, the 3 alternate costumes are the 3 primary colours.
All of these colors go with Zelda's costume and come from the same game as Zelda's.
All of Yoshi's costumes appear as different variations of the Yoshi species in many of his games, such as Yoshi's Story and Super Mario World.
All of Young Link's colors are exactly the same as Link's, except ordered where the black and white costumes are switched.
