Change the message for some players.

How can I change the message sent to some players.

event.setFormat(); works to change the message but I want it to change the name color depending on who is receiving it.

lets say playerA has the permission "namecolors.green" and playerB has "namecolors.red"
how can I make playerA's messages have green names and playerB's messages have red names?
not when they send them but receiving the messages.

does this make sense?

 

Wait so like this:

From a GUEST perspective of a conversation:
Terry1212: Hi guys

From a member example:
Terry1212: Hi guys


I won't work the way you're trying it. When you set the format of a message in the chat event, it sets it for the whole chat, which is all players. A different way to still do something similar, would be to cancel the chat event if the player is a 'special player', store their message and then send it again with sendMessage() method, and permissions.
