1. Download and install, then activate it in Xposed Installer and reboot.
2. To use, just run the app and say you want to change the holo dark background, just tick the color and choose the color you want from the color picker, then soft reboot. Or if you want to use a custom image, untick the color option and choose the image from the Gallery then soft reboot.
NOTE: Changing from color to image and vice versa always require a soft reboot. Changing from one color to another color always require a reboot. And changing from one image to another image does not require a reboot.
