The Pigment Genuine Madder Lake (Pink) by Nila Colori is prepared by extracting the dye from the roots of Madder (Rubia tinctorum, also called Garance). This is a plant, whose root contains a certain number of red coloring molecules. The most famous of these ones is alizarin, which was also one of the first colors to be sintesized in laboratory. The other coloring principle is purpurin, which has a lower lightfastness than alizarin. The color extracted from madder has the best fastness within the plant based ones: lake pigments prepared from this root have been used during the centuries by painters for their beauty too. Nila Colori has used the traditional process followed since centuries to prepare the Pigment Genuine Madder Lake. This pigment is very transparent.
Compatibility: Madder lake will decompose if it’s used together with lime (for example in fresco). Raw earths can fade it; this doesn’t happen with calcined ones (or burnt ones). It fades with some chemical colors like zinc oxide, lead whits, Naples yellow, chrome yellow and green yellow, while it’s stable with other pigments like cadmium yellow, vermilion and carbon black.
Use: In fine arts mostly for the preparation of watercolors and temperae. It is also suitable for oil painting, especially for glazing.
Lightfastness: BSW 6/8
