Petaluma, CA has many interesting old industrial buildings, many of which have been converted to restaurants and shops. This building is one of those and is located on the very end of the San Francisco Bay so a picturesque setting. My palette for this painting is Ultramarine Blue, Alizarin Crimson, Cadmium Yellow light and Titanium White. I use Gamblin Oil paint. This was a difficult plein air painting as there were so many planes and features but I think it came out nicely.
