Creating a Grisaille

     A Grisaille (from the French gris, meaning "gray") is a monochromatic under painting that is used as a foundation for a glazed work.  In this case, I will be using Mars Black, Raw Umber, and Titanium White.

     For a medium I'm using a modern product by Gamblin called Neo Meglip.  It has a soft, silky quality of a gel that will not yellow over time.
