Practicing Plein Air in Casein

I like casein because it is so creamy and goes on the paper easily. It looks just like gouache when on paper but I like the feel to casein better. I also like the smell.

Last night I prepared an orange rectangle on my sketchbook page because I wanted to see how opaque the paint was and how it would look on an orange background. I am still working at getting a pure clean color so I don't think the orange background was a good idea. The colors look a bit muted. This might be due to the medium or just my way of applying the color.

I will probably keep working in Casein for a little while.
