Zorn Palette Study

In my continuing quest to get nicer greens I thought I'd take a different approach. I've been experimenting on reducing my palette to 6 colours + some earth tones and this led to going down to 4 using the palette often associated with Zorn. This was done with Yellow Ochre, Cad Red Light, Lamp Black and Titanium White. It was interesting and challeging but it did get me thinking about colour theory a lot more. I think I will try this again with a different red and yellow and change the black to a paynes grey.
