It appears the manufacturer did not list the pigment(s) for this paint.
Vasari Terre Verde Ancienne Extra Pale is a light, pale grey that leans toward cool green every so slightly. It makes an interesting companion pigment to Vasari’s Cypress Umber Green Extra Pale, which despite having green in the name, leans slightly toward a cool red while being very neutral. Vasari’s Terre Verde Ancienne Extra Pale is an interesting neutral grey green. This color is vastly different than the chromatic and mint green Terre Verde Brentonico Extra Pale, which is noticeably blue green in a pale tint.
This color is part of the set called The Renaissance Touch of Color. Here is what Vasari says about the set, as their brand statements here may shed more light on this individual color as an opaque pigment blend. “Uniquely formulated from the delicate transparent and semi-transparent natural earth pigments actually used by the Renaissance Masters of painting, this set of eight opaque tints offers subtle notes of light. Useful as whites for delicate changes of value or as neutrals to modify brighter colors for suggestions of space and time.
The eight extra pale colors in the set offer a range of warm or cool, exquisite color, and soft neutral tones.” -Vasari
