Tonal gradations, first developed in the Deny paintings, are taken still further in this screen print series. Color and tone play with and against each other to set these ovals in motion. The stenciled effects of screen printing, which involves successive layers of ink, allow for precision in the forms and consistency in the flat planes of tonal color.
