Change Discord PTB icon color

Next to the standard Discord client, we also have Discord Canary and Discord PTB.

And the issue I would like to address here is that the Discord PTB version has the exact same icon as the standard version. Canary's icon is yellow. My suggestion is to make PTB green:

(I tried changing the icon myself but it changes back on updates)

When both standard & PTB are running, there is no way to tell them apart in the taskbar.

Hovering over them only shows a preview of whatever you have open in that client but no indication of it being the standard or the PTB until you open it and see what servers you're in etc.
