In the first edition of The Design of Everyday Things[0], Norman has a photo of beer tap handles on control levers in a nuclear power plant control room. This was done, to differentiate two important handles.
I won’t link to the photo, because it’s on personal blogs, and I don’t want to hug anyone’s site to death.

The photo was removed, in the current version.
