Here you can find Colors 11, 12, 13, 14, and 15 to buy for various amounts of Fight Money, but only if the character you want a color for is at a certain level. In the game's Shop you will find a section to purchase more colors for specific costumes. Here is a table of which difficulties you'll need to complete to earn each color: Unfortunately, this is the only way to get these colors so you'll need patience to get them all. When playing Survival Mode you will only unlock the extra colors for the outfit your fighter is wearing without having to buy it after. For each difficulty you complete you will get more and more colors for that character. The remaining colors must be earned with total victory in Survival Mode. You start with Colors 1 & 2 for all costumes.
