Costume

Color changes, or Tints is a new feature to the Smash Flash series. It is planned to run similarly to the Super Smash Bro.'s Costume changes. It's possible that some tints can make your character resemble other characters in their universe.

Super Smash Flash
There was no option to change a character's color.

Super Smash Flash 2
In Super Smash Flash 2, the player may choose to add a tint to their character based on the team of the individual character's ie. from only red, blue or green (for now). To the disapointment of many people, costumes are not used because they would increase the file size dramatically. Evilgram developed a piece of code which would have supposedly allowed the use of costumes via replacing the colors of already existing sprites, but it turned out either the code wasn't able to do so or Cleod was not able to utilize it.
