Yellow Ochre
Irgazin Yellow/Azo Green
Phthalo Green Blue Shade
A rich sap green made from a yellow earth, azo green, and phthalo green that leans blue. This color is a strong tinter. Williamsburg’s Sap Green is middle green with a deep starting point and that note of slight desaturation needed for foliage greens. A similar color with a looser consistency and less tinting strength would be Schmincke Norma Sap Green. Overall a powerful Sap Green with strong tinting capabilities, a deep starting point, and relatively chromatic in mixes.
This color is also part of their Landscape Colors series: “An excellent outdoor palette that allows artists to produce the wide variety of hues, shades, and tints encountered in nature.” Note: In 2015, this color was reformulated to have greater lightfastness (see https://justpaint.org/beauty-and-the-best-wrestling-with-changes-in-williamsburg/). The previous version was PY42, PG7, PY83, but the blend was not as lightfast as they wished. The formulation changed to PY42, PY129, PG7. At the time of the reformulation the estimated lightfastness of the new blend was ASTM II. In 2023, Golden released new lightfastness information about mixing white combinations. As a mixture, this color does not appear to have been specifically mentioned, however some of its ingredients are. It is worth noting that Golden published groundbreaking lightfastness testing in various white colors. The choice of mixing white may affect the performance of certain pigments.
