I am working on a painting where I used only Ivory Black and Liquitex Heavy Body White. It is monochromatic and you can mix to get grays. I will enter it in the Tiffin Art Guild's new competition and show, called the Black & White Show, in two weeks. Untitled so far. 20 inches wide. Sixteen tall. In this 'in-progress' photo on the easel it is about half finished.
