Forums Scripts & Popups Using the nick list color in messages

I want it to do it automatically for all the nicknames.

For exemple here is the list of the users : User1, User2, User3

When someone type a message with theses 3 nicknames, I want it to appears in the same color than/in the list. Like that : < Random > Hello, User1, User2, User3 !

And I don't want to configure it manually in the "Nick Colors" because there's a lot of users... I'm not going to do this for each users.
