📜 Origin & History

Sap Green is an organic pigment extracted from the ripe berries of buckthorn plants. Medieval manuscript illuminators had already begun using this warm, transparent green to depict vines and leaves.

From the Renaissance to the Baroque period, Sap Green was a core pigment for transparent glazing in oil painting. Artists layered thin washes of Sap Green over a lead white underpainting to create gem-like deep green robes and foliage.

In the Dutch Golden Age of the 17th century, landscape painters like Hobbema and Ruisdael used Sap Green extensively. Its warm, transparent qualities infused Dutch skies and woodlands with a poetic sense of light.

The drawback of Sap Green was its poor lightfastness, causing it to fade easily. In the 18th and 19th centuries, with the advent of stable synthetic pigments like Viridian, Sap Green gradually receded from the painter's palette.

Contemporary pigment manufacturers have developed 'Sap Green Hue' paints using modern synthetic pigment mixtures, preserving the original's warm, transparent character while drastically improving lightfastness, allowing the classical beauty to endure.
