Etymology: Chromatosis is a plain technical coinage built from two Greek-derived parts. The first, "chromato-", comes from Greek "chrōma", meaning colour, and the second, "-osis", is a suffix denoting a condition or disease, as in "neurosis" or "thrombosis". Put together, the name describes an abnormal condition in which colour has accumulated in the skin or tissues. The term belongs to the vocabulary of modern medicine rather than ancient Greek. Physicians of the 18th and 19th centuries built many such names by joining classical roots, so the word reflects the scientific practice of that era rather than any everyday use in antiquity. Its meaning stays literal: the excess of pigment or colouring is the entire point of the name, and the word is applied to a range of conditions with different causes.
