What I mean is black comedy (or dark humour if you want) is a subgenre of comedy that consists to make light of otherwise serious topics (in other words, serious and horrible things played for laughs).
The opposite would be drama based around making dark of otherwise comical topics (in other words, funny and great things played for drama).
I would call that white drama/lighthearted tragedy.
Also, could you give some more or less famous examples, please? The only one I can think is Waiting For Godot (1953, Ireland/France, Samuel Beckett).
