For laughs, there is a hundred year old Hungarian/Serbian hard candy called Negro. The author's name was Pietro Negro, and the candy is charcoal black because of liquorice and doped with menthol, which gives it a distinctive medicine taste. People love it or hate it, I love it personally. In the meantime, more flavours are developed in Serbia, with eucalyptus, peppermint, lime, caramel... And all of them called Negro because it's just a strong brand name.

Nevertheless, every once in a while there is some wiseguy trying to make a story out of it, just ruining the fun. If we really want to take that discussion, I would argue that it's actually an homage to people of color, being so popular yet unrelated to colonialism or slavery and treated like a folk remedy for a sore throat.
