Other forms: pigmentations
Pigmentation is the natural tint or color of any living thing. The black pigmentation on your dog's tongue is one clue that she may be part chow chow.
Use this fancy word to mean "color," especially when you're talking about plants or animals (including people). The bright green pigmentation of a tree on your block changes to deep orange by mid-October. And the pigmentation in your skin may be slightly darker than your brother's. The word pigmentation comes from pigment and the Latin pingere, "to color or paint," a root it shares with the English word paint.
