The underpainting of Fastmatte paint dried very quickly. Too Quickly for my technique. And so, today I am repainting the background. I purchased a new color "Sepia" for my trip last June to the IMC and never used it while there. As a matter of fact, I had never used Sepia before. Since I am in an experimental mood these days, I pulled it out this morning and have been using it in the background to get a very rich greenish black/brown color. Very Nice!!! Almost as nice as my Sap Green and Alizarin Crimson background mix. Pictures to come shortly......when there is something that you can recognize on the canvas.
