The noir sky was fun to create and experimenting with the colors on top, first with one knife, then replicating with another was a great exercise. I made two final paintings but started with a few composition and color studies on gessoed bristol board to decide how I wanted to use the knives and the colors. I liked experimenting with lots of blues and pink combinations to get the results in the final paintings.
You can see in some of the different process photos the different textures and shapes you can achieve with a palette knife. It's also fun to see the color notes for the sky from the top of the sky down to the horizon: Prussian Blue, Ultramarine Blue, Pthalo Blue, Alizarin, Cad Yellow + White.
