As I was setting up my new series of painting, my wife comes in, plops a pear on my table and says "Paint this."
So, what choice did I have?
I painted it on a piece of water color paper I had primed with a neutral grey acrylic.
I used gouache paints, and started with the bright orange background first, then worried myself over the color of the pear. A little lemon yellow, some phthalo blue, and titanium white and I was good...
