A couple of weeks ago we plein air painted on the corner of Occidental Road and Sanford Road here in Sebastopol, CA. The mustard fields were in full bloom and here is my interpretation of them and this beautiful farm at the top of the hill with mountains in the background. My palette for this painting is Cobalt blue, Cadmium yellow light, Napthol red and Titanium White. I use Gamblin oil paints. It was a spectacular warm day here in March.
