Here are some examples:
* Le chat du noir: The black cat
* Un ciel du noir: A black sky
* Le vin du noir: Black wine (referring to red wine)
* Un film du noir: A film noir (a genre of film known for its dark and often cynical themes)
It can also be used metaphorically to describe something that is dark or negative, such as:
* Une histoire du noir: A dark story
However, "du noir" is not a stand-alone word in French. It is always part of a larger phrase.
