Black in Burgundy
I believe the answer is:
'black in burgundy' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for noir that I've seen before include "Film featuring bleak settings and cynical characters" , "film genre" , "Dark in France, like brooding films of 40s and 50s" , "cinematic style" , "Kind of dark film" .)
