Description
I have struggled to find a good blue black before, Winsor and Newton make one which is passable but a long way from a handmade, high pigment paint.
This is the best one I have used, it is deep black hue with cool bluish tints. The small amount of Prussian blue in it's makeup gives a real depth to it's opaqueness, it is not a flat black. It makes beautiful violet tints.
Rublev- "Blue Black appears in the catalogues of artists’ colourmen circulated in the nineteenth century. Some references describe it as charcoal black, which may have been derived from charred vine cuttings or wood charcoal. It is often listed as a mixture of 40 parts bone black and three parts Prussian blue, which is the composition of Rublev Blue Black."
