Good old ivory black, the cool black based on carbon deposits from burnt bones and the most common black.
This is version is very finely ground and super smooth, not at all greasy like some.
Well in masstone it is black! When white is added the familiar blue greys emerge.
Some versions can be so cool they can be used as a blue, for example in the Zorn type palette, this would be suitable for that.
Expertly ground with French artisanal linseed oil, beautiful paint.
