Cadmium Yellow
Viridian
A lovely leaf green. Our tube of this color is from the olden days of Williamsburg, that is, before the label typeface change. It is a very attractive hue of bright green, not an unnatural green (which have their own uses), this is middle-lightness tone of high-chroma foliage in sunlight. On the chromatic edge of the foliage greens, it has a pleasant tonal relationship with Williamsburg’s Cadmium Green. See that color for a brief note about convenience greens. This color is strongly pigmented and has good tinting strength.
As a mixture, this color does not appear to have been specifically mentioned, however 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. See https://justpaint.org/astm-lightfastness-testing-for-oil-paints/ for more information.
