Notes on Meaning

The two primary meanings are intrinsically linked. The color is named after the chemical compound, which was a popular source for that specific shade. Modern usage almost always carries a historical connotation, referring to the pigment's use in art or its role as an early pesticide. It is not a term for a generic green color in contemporary language.

Noun
