You'll need to enable the "Desktop Experience" feature to get the desktop parts (color schemes, 3d graphics, windows media player etc). We do this on our terminal servers. You might have to force users into using a defined style - this can be done via the local group policy or in a regular domain based GPO.
Once installation finished, you need to right click on desktop :)
You may use display option given under control panel.
Control Panel > All control panel items > Display > Change Desktop background > Picture Location > Solid Colors > Choose any color > Save changes.
