Definition

1. Noun:

   • A green or bluish-green coating that forms on copper, brass, or bronze surfaces: This coating, also called a patina, is a result of chemical reactions (corrosion) when the metal is exposed to air or water over a long period.
   • A blue or green pigment: A powder, historically made from this coating or a synthetic equivalent, used in paints and dyes.

2. Verb:

   • To color or coat something with verdigris: To give something the greenish-blue color characteristic of this substance.
