This color is a warm fir green that in masstone, is low in lightness, around a value 3. While being a sort of fir green the yellowness is noticeable, perhaps placing the hue around Munsell 2.5GY. Unfortunately Vasari does not disclose the pigments they use in this convenience mixture, however at least of them is Cadmium Yellow. Interestingly, this hue goes neutral in tints with Titanium White. The tints are not a true neutral, and retain some of the character of the masstone. Nonetheless we can see why Vasari mentions bringing shadow to a mixture. Overall we were pleasantly surprised by the Scott Christiansen colors as a set. Vasari’s Jasper has a nice relationship to the other colors in the set while providing a green baritone or even bass note.
