As the documentation string says: "Set nil (default) if you want Emacs
to examine the brightness for you".

I think the [default] button is misleading into thinking it has
something to do with the default value of frame-background-mode.
Perhaps it should be changed from the button to ordinary text,
because the [Value Menu] button prior to it has the same menu
for selecting its value.  Also the tag "default" could be changed
to something more descriptive like "default brightness".
