This new painting in green and white felt too monochromatic to me when I looked at it the next day. So I began to jazz it up with bright yellow, cadmium orange, and pthalo green. This time instead of a palette knife, I used a brush.
I ended up covering over almost the whole canvas, though the basic composition remained. I let the colors blend, so that the yellow, white and green became a lime green in places.
I painted the background over with parchment, and added that to the mix of colors in the main composition. Then I added lines in Prussian blue, feathering them with the brush.
Even though this painting is now signed, I will keep working on it, as I already see things that I don't like about it.
