What does mottling mean?
Mottling is an irregular pattern made up of patches, spots, or streaks of different colors. It can describe a naturally variegated surface, such as an animal's coat, a stone, or flower petals, as well as an altered or distressed appearance produced by age, wear, or photographic processing. The word suggests unevenness and visual variation rather than a regular design. As a noun, mottling usually names the overall effect, while individual colored areas may be called mottles or patches. As a verb, mottling describes a surface becoming marked in this way. The term is useful when discussing pattern, texture, coloration, and change, especially in natural history, art, materials, and photography.

Where does mottling come from?
The word is an English formation based on mottle, with the ending -ing used in its verbal form. Mottle and mottled belong to an English vocabulary of colored patches and spots that developed through Old French; the precise origin of the older French source is uncertain.
