NameColors

The NameColors plugin (source code) is a plugin used on some civ servers to give donators the ability to change the color of their name in chat messages. It also changes their name on the tab menu.

Configuration
To configure your namecolor, use the  command and select the NameColor option. Note that your minecraft account first needs to have permission to configure a namecolor - this may happen automatically once you donate, or you may need to ask the admins to give your account permission after donating.
