Aura Colors
The following have been used; when creating a sailor, pick something not too close to any of them. If you need ideas, you can go here for a big list of colors to choose from, or try Wikipedia's list. Don't pick black or white either; black is reserved for Bad Guys and white is already the bodysuit color.
