I did this quick little 10x8, oil/canvas this afternoon in the back yard as a rumbling thunderstorm was blowing through just to the north. I worked with a limited palette of Titanium White, Ivory Black, Cad Yellow Medium, Cad Red Light, Ultramarine & Ceruleun Blue. I used Liquin as my medium. The sunlit edges of the dense clouds shined against the blue of the sky. I also liked how the sunlit hotness remained constant on the blowing bamboo and kept the heat of the reflected light in the shadows.
