Cobalt Blue, a single pigment paint, is a semi-transparent paint with moderate tinting strength. Cobalt Blue is a slightly cooler blue on the color charts, and is a classic choice for the traditional palette. Cobalt Blue is also referred to as Parrish Blue, after the artist Maxfield Parrish for using it especially when creating his incredibly rich skies. A great mixer, but so rich it is often used as is.
