ok guys this is a very special thing that I found out about. to change the cloud of your name you must do /nick (if you can't then don't bother). do /nick &1 or &2 or &3 or &4 or &5 or &6 or &7 or &8 or &9 and then type your name e.g. /nick &1niterider11 and then your name would be blue you could also do /nick &1n&2i&3t&4e&5r&6i&7d&8e&9r&11&21 and that would be a rainbow name

hope this helps
