What does depigment mean?
Depigment is a transitive verb meaning to remove pigment from a substance, tissue, or surface, usually making it paler or completely colourless. The word is especially common in scientific, medical, and technical writing. In dermatology, depigmentation can describe the loss of melanin and the appearance of pale or white patches of skin; in chemistry and biology, it can mean removing the natural colouring matter from a material or organism. Depigment is more precise than a general word such as bleach, because it identifies the removal of pigment as the relevant process. It is usually followed by a direct object: one can depigment skin, hair, cells, or a material. The related noun depigmentation names the process itself. The prefix de- indicates removal, while pigment refers to the colouring substance. Together, these elements make depigment a useful word when the disappearance or extraction of colour is the central idea.

Where does depigment come from?

The formation is transparent in meaning: to depigment something is to take pigment or colour away from it. English cognates and related forms include pigment, pigmented, pigmentary, and pigmentation, all sharing the same Latin root.
