Pompeian red
Pompeian Red refers to the color of an iron oxide-based mineral pigment. / From Wikipedia, the free encyclopedia
Pompeian red refers to the color of iron oxide-based mineral pigment with a hue close to red ochre, so named because of its common use in ancient Roman painting and the fact that it is abundant in the murals of Pompeii. Studies have shown that walls with Pompeian red backgrounds were painted in various ways,[citation needed] of which the use of cinnabar was the most expensive.
This term also defines the ochre-red color of a plaster characteristic of Roman ceramics.[1]
