What does pigmentary mean?
Pigmentary is an adjective meaning relating to pigment, the substance or process responsible for coloration. In biology and medicine, it is commonly used to describe structures, changes, or conditions involving pigmentation, as in pigmentary retinopathy, pigmentary glaucoma, or pigmentary changes in the skin. The word is more formal and technical than pigmented, and it can apply both to pigments themselves and to the biological effects associated with them. Its Latin roots connect it with painting and coloring: pigment originally referred to a coloring substance, while the adjective pigmentary developed to describe what is connected with such coloring. Although pigmentary is not encountered constantly in general conversation, it is useful when precision matters, particularly in scientific descriptions of how living tissues and organisms receive, contain, or lose their color.
