  No, because the default ambient term of lighting is not zero. (If you set
it to zero then it would be so.)

  Are you explicitly specifying "#version 3.7"? Because that turns on the
new gamma correction scheme, but you should also get a warning that you
should also explicitly specify an "assumed_gamma" in your global settings.

  If you don't explicitly specify "#version 3.7" then the old gamma scheme
is assumed by default.
