I wasn't sure whether or not to consider this painting "finished" or not. I suppose it could just be a semi-abstract landscape. I did, however, like the color scheme which was a pretty limited palette of: Cadmium Red Dark (Classic Artists Oils), Quinacridone Red (Classic Artists Oils), Hansa Yellow Orange (Classic Artists Oils), Cadmium Yellow Medium (Utrecht), French Ultramarine Blue (Winsor & Newton) and Titanium White (Winsor & Newton).
Normally, I would have used Gamblin Galkyd as a medium, but this was a lunch hour painting and all I had were my paints, the board and a palette knife.
I started out with a very thin underpainting (on the land and rock area only) with the Quin. Red and the Hansa Yellow Orange. Hansa Yellow Orange is like Indian Yellow in other brands, but I particularly like Classic Artists Oils' Hansa Yellow Orange better. In the dark areas, I used a combination of the Cad. Red. Dark and Fr. Ult. Blue.
The gray in the painting was made from all the colors in the palette scraped together with a bit of white added to get the right value. I rather like it.
