I wanted to keep this painting fresh by not overdoing my paint application. I like an orange underpainting (which was dry) because it really vibrates the sky color. I used a mixture of Ultramarine, Viridian and Alizarin to lay in the dark shapes in one take. For some reason, I have strayed from this mixture and it feels like coming home to use it. It's a very versatile transparent dark and you can lean it towards any of the three colors. By adding white and some orange you get beautiful harmonious grays throughout the painting. I used an appropriate amount of red in my greens to push them back in the frame, and applied my paint stroke by stroke, wiping my brushes in between to keep the color fresh. I was never a one brush painter because some colors just need to be separated, but there is something to be said about limiting brushes to a few to keep the color harmonious. My husband thinks that the building needs some windows on the right side, but I just want to darken it with very carefully placed brushmarks to set it back more. It's too light to be the shadow side of the building. Maybe another stroke on the truck too. What do you think?
