Black, History of a color in France #REPLAY

I wrote this short rap in french with french expressions that give a negative connotation to the word « Noir » which translate to Black or Dark in English depending on the context. I know in English, you have expressions such as black market, to blackmail, black sheep, but in French, there are so many of them that it becomes legitimate to ask whether they do not have a consequence on the perception of black skinned people in France. How did we get to such reality when it is well known that, from antiquity, black color was synonymous with ceremonial and prestige ?
