This is a quick exploration of the use of a chromatic black under painting using ultramarine blue, burnt sienna and titanium white. My darkest darks are the chromatic black, my far greys are blue bias, and my near greys blue bias/warm bias. I used a size 10 filbert on an A4 sized board. To speed up the drying process my pigments were mixed with Liquin.
