I have found that drawing with white on black is challenging but interesting. The results pop in a weird way that drawing on white paper doesn't. It also puts me in the mind of one of my ART SAINTS, Keith Haring. He'd do these quick chalk drawings on the black paste overs on ads in the subway that were ephemeral moments of urban beauty. I also think of X-rays. These (mostly) monochrome images give me a feeling of seeing into or under the skin of a picture.
