The Pigment Genuine Weld Lake by Nila Colori is prepared by extracting the dye from Weld (Reseda luteola) plant. This is a plant largely widespread in Europe producing luteolin, a yellow colored flavone. If the coloring matter of weld is fixed on a mineral base, a yellow lake is obtained. Nila Colori has used the traditional process followed since centuries to prepare the Pigment Genuine Weld Lake. This pigment is very transparent.
Compatibility: Weld lake will decompose if it’s used together with lime (for example in fresco).
Use: In fine arts mostly for the preparation of watercolors and temperae. It is also suitable for oil painting, especially for glazing.
