I am trying to change the appearance of notification icons (the ones located at the right bottom of the screen). I know how to make the icons not show up, but what I want to do is swap the current icons for different ones that match the style of my desktop. How do I change them? Do I need to download a program?

What do you exactly mean by swapping notification icons? Do you want to change the appereance of the notification icons that matches with the desktop style?

You cannot change the appearance(colour) of the icons on the notificaiton area.

You may use your favorite search engine and download any third party program which would help you with this.
