Anybody know how to do this? The background color of the battery charging screen is black which conflicts with the theme I created. I know how to change the battery images to customize the battery, but I simply need to change the background color from black to white. The thread below is all I could find on this:

MacThemes Forum / Background Wallpaper for Charging Screen?

It has to be possible to change this without using an .html file. Anybody done this? Thanks for any help.
