red lead
Orange anticorrosive pigment
Red lead is a bright orange-red compound of lead oxide, historically used as a pigment in paints and primers, especially for protecting iron and steel from corrosion.
It appears in old buildings, ships, and bridges.
Due to lead's toxicity, its use has declined sharply, though the term persists in industrial contexts: The old railings were coated in red lead primer.
