Most of us have not had to deal with a gobal health emergency. Even the experts are trying to "make good guesses" - trying things and see how they work. And there are a lot of experiments going on.
I like doing my experiments on paper with pigment.
Each of these six paintings has been done with just two pigments.
Yellow Burnt Ultramarine Chromium
Ochre Sienna Blue Oxide Green
(More black added)
