Vine Black a warmish black used to be made with the Carbon derived from burnt vines. This is my personal favourite out of Michael's blacks. It has a bit more substance in handling than the others, although it is certainly the warmest as well.
Possibly better suited to colour mixing being semi-transparent, less likely to 'muddy' mixes.
High pigment load, very good value paint.
