Alternatives to burnt umber?
My go to black is French ultramarine and burnt umber. It's easy to pull it warm or cool, I like it. Current tubes of both are Gamblin. This latest painting has a lot of darks and so everything has that dull umber flatness. It feels horrible. I don't want to oil out all the time, and I don't use retouch varnish for technical reasons. So I have to live with it for now.
Does anyone know a good alternative to burnt umber?
