till Marshmallow, we were able to add only 5 favourite contacts to "People Edge" & we were able to assign 5 colours to those favourite contacts. So that, whoever calls from those favourite contacts, we use to have lighting when we get incoming call. But in Nought, it's been removed. Means, we don't get different colours at the time of incoming call. But we can add 10 favourite contacts to the People Edge Menu
