I figured it out! Yay! Btw if anyone's wondering here's a quick explanation from Legitmon in another thread:
Easy way to remember colors:
& = Character to place before the /Nick
1-9 and a-f = Colors ID tags, you place after /Nick &
l u n m = crazy other tags, you place after /Nick &(color)&
Example: /nick &bApple
/nick &4&lApple
/nick &5App&9le
