How do notification lights work on the samsung galaxy s6 edge?

[AC Question]

When you set the phone face down, you can recieve a light notification based on the person trying to call/message you. For example, mom can equal red and dad can equal blue. But can you set it up to recieve light notifications for things like email equals blue and text message equals red?

Also, can you make it so if you're getting a call, you can recieve a light notification and hear the phone ringing? If you assign a notification to your 5 favorite people, will you recieve a light notification from someone other than those 5 people?
