Changing Item color

Alternate object color option might not be working? I can't seem to change it from black

  Depending on the browser it might be a little tricky. 

  1.         select the object you want to change
  2.         go to the object inspector
  3.         click on the colored rectangle
  4.         select the color using the pop-up window
  5.         Once you selected the color , you have to click on the rectangle again to register the change.
