Why is my code running on everyone

Okay, so basically I made this plugin, and it works fine, but when I run it on my server, (i.e if I run /setcolour red) I will see everyones name as red,
How can I make it so ONLY the person who runs the command or the 2nd argument on my command /setcolour?
this is my first plugin and so far so good it's just this little bug, if anyone could help I would much appreciate it,
Here is my source: http://pastebin.com/raw.php?i=GwVX2KNP
Thank you!

Just realised I screwed up the thread title, I renamed it. Still looking for help though, much appreciated.

PlayerRecieveNametagEvent is for all players, unless said otherwise.

 

Code:java

public boolean onCommand(CommandSender sender, Command cmd, String commandlabel, String[] args){
    if(commandlabel.equalsIgnoreCase("setcolour"){
        if(args.length == 1){
            Player player = (Player) sender;
        } else {
            Player player = Bukkit.getPlayerExact(args[1]);
            if(player == null){
                sender.sendMessage("Player is not online!");
                return true;
            }
        }
        // Rest of Code Here
    }
}
 
 

Also, to make the class a little shorter, change the setting of the tag to happen in the command

Not sure it it would work but when you type the command everyone is added to a list and then you remove the sender, then everyone in the list has that name color except the sender. bloodless2010
