The story of the word

Chemists named the pigment in the 19th century from the ordinary Greek word for black. One substance does several jobs with it: colouring hair and iris, darkening skin under sunlight, and soaking up ultraviolet before it reaches DNA. μέλας also sits inside melancholy, the black bile that ancient medicine blamed for depression, and Melanesia, the black islands.
