Cobalt Chromite Green Spinel
PG26
Alternate Name
Cobalt Chrome Oxide
Pigment Description
Cobalt Chromite Green, one of the secrets of the realist painters' palette. While it's not for everyone, this color has a useful role in mixing, especially for naturalistic work. While in masstone it is not exactly a showstopper- a duller deep green- in blends it is helpful for creating muted colors. Like many cobalts, it comes in a range of greens with some being warmer and some cooler.
Mussini Turmaline Green, PG26
It is rated a B for toxicity, so we'd place it among the toxic pigments. If it does contain some soluble chromium that's a toxic issue, so do avoid all contact with your mouth, don't breathe dust, etc. Please treat this with all due respect and caution just in case.
