I'm developing an application which needs a "Night Display". The "Night Display" should be able to change the colors for every application in Windows NT (including Desktop, Mouse Icon, Taskbar....) I could change the color of every single object, but that is not satisfactory. The functionality I'm looking for is very much like the functionality in the Control Panel. I need to be able to change the Scheme and colors for every item. Preferably I would like to be able to save/read these settings on/from a file.
