一種鹼式鉻酸鉛顏料，色澤由棕黃橘至磚紅，依粒子大小及鉛氧化物與鉻酸鉛兩者的比例而定。鉻紅由沃克朗（Vauquelin）首度製造於西元1809年，加熱鉻酸鉛與氫氧化鈉溶液，形成鹼式鉻酸鉛。由於與大氣中的硫接觸後傾向轉棕、會與其它顏料相互作用、暴露至陽光下會轉綠，鉻紅因而不做為永久性顏料使用。鉻紅最常做為鋼的防腐基底塗層。Basic lead chromate pigment that ranges in shades from brown-yellow orange to a brick-red color, depending on particle size and the ratio of lead oxide to lead chromate. It was first made in 1809 by Vauquelin by heating lead chromate and sodium hydroxide solution to form basic lead chromate. It is not used as a permanent paint due to its tendency to turn brown on contact with sulfur in the atmosphere, react with other pigments, and turn green with exposure to sunlight. Most often, chrome red is used as an anticorrosive base coats for steel.
