Using the Auto Colour Feature
The Auto Colour feature is to be found on the “Format” ribbon.
Auto Colour is designed to give each series of branches coming from your core a different style.
(The colours defined through the auto colour dialog do not relate to the levels of branch in your map – i.e. All subsequent child branches will inherit their colour from their parent).
