Black was one of the first colors used by artists in neolithic cave paintings. In the Roman Empire, it became the color of mourning, and over the centuries it was frequently associated with death, evil, witches and magic. In the 14th century, it began to be worn by royalty, the clergy, judges and government officials in much of Europe. It became the color worn by English romantic poets, businessmen and statesmen in the 19th century, and a high fashion color in the 20th century.

In the Western World today, it is the color most commonly associated with mourning, the end, secrets, magic, power, violence, evil, and elegance.
