For some reason, my ubuntu wallpaper suddenly turned black and white. If I try to change the desktop wallpaper image it always shows in black and white only (i.e. no color). Where the heck can I change this strange behavior?

I'm running the xubuntu desktop (i.e. xfce) on an ubuntu 11.10 installation (switched to the xubuntu desktop after giving up on unity).
