!!!BIG UPDATE, READ INSTRUCTIONS!!!
Because of recent Samsungs changes, there are more steps required to make this application function again. First, enable all the applications that you want to use with edge lighting in this application. After that, go to Settings / Display / Edge Screen / Edge Lighting / Edge lighting style / Color / Custom color and go into section By text. Here you input all the application names, which you've enabled in this application and select colors for them. After that, it will work because this app will trigger a new notification with application title and it will trigger original edge ligthing effect.

As of latest Samungs update of EdgeScreen, they disabled custom colors for notifications. They are overwriting any color changes made by any app. If you want to have this app running well, please do this:
Please go to Settings / Apps / EdgeScreen and in top right corner, tap on three dots to show menu an Uninstall all updates. After that, go to Settings / Display / Edge Screen / Edge Lighting / Manage notifications and enable my app.
I am currently trying to solve this issue, but it will be hard and maybe I need som assistance from Samsung.
To ensure, that your phone is set correctly, or you have any problems, try this at first:
Go to Settings / Display / Edge screen. Here please tap on Edge lighting and make sure it's set to Always. Also tap on Edge lighting style, tap on Color / App color and in top right corner tap on three dots and select Reset app colors.
If application is only waking up your display, do this: Go to Settings / Display / Edge Screen / Edge lighting / Manage notifications and check, that my application is enabled. If it is enabled, try to disable and enable it again.
NOTICE: You need to have enable Edge Lighting notifications in your mobile phone!
Using this applications you can enable edge notifications and customize color for any application installed on your device. Works while AOD too.
This application uses Samsung native notifications, not any emulated notifications. It works by translating old, non-edge notifications to new style notifications.
