I was intrigued by his limited palette. It is said that he only used four colors - referred to as the Zorn Palette. He worked his magic using cadmium red medium, ivory black, yellow ocher and titanium white. How could this be possible? I decided to find out for myself and spent time today creating a color chart using just those colors. I always learn so much about color when I take the time to do an exercise like this.
The first photo shows the color chart next to the book open to a page showing two of his portraits.
Hopefully, it wont be much longer before I can get back to painting.
