Event, Message, Highlight
Whenever a new message is displayed in a channel or query window, mIRC highlights the switchbar icon for that window with the chosen color.
The event color is used for all non-message events, such as joins, parts, modes, etc. The Message color is used for actual messages, and the Highlight color is used for highlighted messages, ie. messages that match your Highlight settings.
