+ You can now set "ChangeOnChat" to true if you want to have the rainbow color changes everytime you chat like in version ChatColor+ 6.2.0 and below. if its false (it will be false standardly) it will be the same rainbowcolor for everyone everytime.
+ You can now choose which colors are used when someone is using the rainbow color. just remove the colors you dont want. (see screenshot below).
