Recolor/Palette Swaps help

[Vipershark]

What characters are you putting in to begin with? Unless you're including every character that's already in the official games, it's a bit pointless to suggest colors for characters that might not even get in.

Even so, the "idea stage" isn't really the right time to worry about what palette swaps you'll have. You should be focusing on the "actually making a game" part.
