Playing with System Settings/personal/Appearance in 11.10. Looked at High Contrast in drop-down and it applied. Now I can't find a way to turn it off. Any ideas?

Ubuntu 9.04 had a way to change login window under System->Administration->Login Window. Now the feature is missing. All i can find is a Login Screen menuitem but it doesn't have any option to change the appearance of login window. I tried searching synaptics manager and still no luck.
