LoneColor is very easy to use: simply drop the application or its shortcut on your Desktop and double-click it: you will get a random color wallpaper. Rename "LoneColor" to "LoneColor Pink", run it, and your Desktop will get a Pink wallpaper. LoneColor has a minimal design and no Graphical User Interface. To specify the color you want to use, just add the color name to the LoneColor program name. It's like using command line parameters, but a lot easier.
