Alternate costume (SSBM)

NOTE: Every claimed source needs a cross-reference link; claimed sources need to be plausible, not horrendously obscure; default costumes usually don't need descriptions since they are not alternate costumes; returning costumes original to Smash do not need references to their appearances in previous Smash games.

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 and afterward, would crash the game.

Strangely enough, alternate costumes can affect gameplay, such as Captain Falcon's model changing sizes depending on the costume.

Bowser

Green	G
Red	R	Resembles a Spiny or red Koopa Troopa. It also resembles Roy Koopa's early in-game sprites without the sunglasses, as well as Bowser's second player costume in Mario Golf. Unusually, while the artwork depicts Bowser with red eyes, they are green in-game.

Black

Blue	B
Green	G
Orange
Red	R

Jigglypuff

Pink
Red	R
Blue	B	Similar to the bows from the original Super Smash Bros.
Green	G
Yellow		The crown that Jigglypuff wears in this costume is identical to that worn by Peach.

Kirby

Pink
Yellow		This color swap is Keeby, who was Kirby's companion in games that featured co-op mode. It is also the same as when he is Beam Kirby or Needle Kirby, without the hat. It was also an alternative palette for Kirby in the multiplayer for Kirby 64. Developer Shigeru Miyamoto also reportedly believed Kirby should be yellow in his debut game, while Masahiro Sakurai believed the character should be pink.
Blue	B	Resembles Ice Kirby, without the hat. It is also an alternative palette for Kirby in the multiplayer for Kirby 64.
Red	R	Resembles Fire Kirby, without the hat.
Green	G	An alternative palette for Kirby in the multiplayer for Kirby 64.

Link

Green	G
Red	R	Based on the Goron Tunic from The Legend of Zelda: Ocarina of Time. It also resembles Link with the Red Ring from the original The Legend of Zelda.

Blue	B	Resembles the artwork for Mario on the cover for the NES version of Mario Bros., though his sprite does not actually feature such coloring.
Pink	R	Based on Luigi's appearance in Wrecking Crew.

Mario

Red	R
Yellow		Based on Wario, the same as his yellow costume in the previous game. Unlike the original (and every other iteration in the series), the colored "M" is blue instead of yellow and the buttons are white instead of yellow, as to make him more closely resemble Wario. Additionally, Mario's hat gains a white accent on its edge.
Black		A reference to Foreman Spike from Wrecking Crew '98. Updated from the original version of this swap to be closer to black and white than brown and yellow. It is the only costume where the hat and overalls are changed to be the same color.
Blue	B	A reversal of his traditional colors. This is seen as a partial reference to Mario's varying appearances in games prior to Nintendo's official establishment of Mario's outfit consisting of a red shirt, blue overalls, and red hat. In various earlier games, Mario occasionally also appeared with a blue hat, red shirt with blue overalls, or a red hat with a blue shirt with red overalls. Interestingly, though, Mario never appeared in any game with the particular combination of a blue hat, blue shirt, with red overalls as it appears here, but this color scheme does resemble the Balloon Fighter and it also resembles Mario's outfit from the DIC cartoons.
Green	G	Complimentary colors of his normal outfit. Resembles Mario's appearance on Japanese and European box arts for Wrecking Crew. A similar arrangement of colors also appears as part of the flashing animation from a Starman in Super Mario Bros. Updated from the original version of this swap to be more brown than orange.

Mr. Game & Watch

Black
Red	R

Ness

Red	R
Yellow		The yellow/black color scheme resembles that of the Hanshin Tigers, a Japanese baseball team. The shirt also bears a very similar color scheme to the Gigantic Ant enemy from EarthBound.
Blue	B	Is based off of Ness's younger self that he encounters briefly in Magicant, who was wearing a blue hat.
Green	G

Peach

Pink	R
Yellow		This costume changes Peach's entire appearance to that of Daisy, including her hair color, earrings, dress style, gloves, tiara, and even skin color. However, later games in the Mario series changed Daisy's design, resulting in the costume only matching games before Melee.
White		Represents how she appeared in her first appearance in Super Mario Bros, without the red hair and red trim. Peach uniquely wears pantyhose with this costume.
Blue	B	Based on a swap from Mario Golf, and Daisy's appearance in NES Open Tournament Golf.
