Stil de grain yellow is a pigment traditionally derived from unripe buckthorn berries. An archaic name for this color used in the 17th century is pinke.It is also known as sap green although in contemporary art supplies the term sap green often indicates a mixture intending to resemble the traditional Sap Green or Stil de grain yellow. Contemporary oil colors often use coal tar lakes as a substitute. Golden Fluid Acrylics have included ‘sap green’ in their new line of ‘historical colors’.
