This is the underpainting I did this morning. I used four colors, one color too many I think. Thalo green, a strong, staining pigment. The powerful strength of the color created the image upon which to build.
Underpaintings are like Rorschach tests--say what you see. I see hollies--with berries. When I go back into the painting that's probably the image I'll develop. Once said, I won't be able to shake it out of my head. Christmas in April. I'll keep in touch.
