Gesso & black

Bob Ross Gesso, in black and grey, is about half the cost of the Golden Gessos. Liquitex “basics” is even cheaper, but only available in white.

Since i didn’t buy a golden liquid black in my last order, it seems that a liquid black and a tub of white gesso might also provide a satisfactory black gesso.

I think bone black is blacker, but that carbon black would “go farther”
