Black
The capitalization “Black” makes it visible that it is not the use of an adjective and accordingly no color is meant, but a political self-designation. Thus, the term attempts to bundle social commonalities that result from the construct of racism. That is, it is about people who experience racism, thus “black” points to a political reality and identity. It is not at all about biological commonalities of a group. White is also a construct. To make it clear that this is also not a color designation but a political description, the term is used in italics.
