It is actually based on a photo of Greta Garbo, but I like to paint in one color washes, so I changed the colors to something I used to work with. It was a choice between Indian red or burnt umber. I opted for Indian red because I knew I had to cover up what was already painted with something dark. My original sketch, such as it was, was based on a cerulean blue sky. When I found this canvas that I had to cover up, I went with a cobalt and ultramarine, midnight blue, sky.
I could natter on forever about this but I don't want to bore anyone here.
