Rose madder (also known as madder) is a red paint made from the pigment madder lake, a traditional lake pigment extracted from the common madder plant Rubia tinctorum.
Madder lake contains two organic red dyes: alizarin and purpurin. As a paint, it has been described as a fugitive, transparent, nonstaining, mid valued, moderately dull violet red pigment in tints and medium solutions, darkening to an impermanent, dull magenta red in masstone.
