Sky as the source of color scheme

The underpaintings shown are a mix of viridian, cadmium red medium and white. Yesterday I applied the first glaze to the square painting illustrated above, a landscape in Northern Portugal. I started the session with a neutralized blue-gray to the sky. My attention was focused on mixing colors to create distant atmospheric perspective. When it came to the foreground greens I found it difficult to mix colors that didn't make my stomach turn and cause a sense of depression to deplete my energy. After several hours of struggle, I was able to mix brighter, yet still grayed, greens and an odd, but not unpleasant sense of light began to give life to the painting.



Today's session started on a second canvas (same underpainting colors) with a different approach to the sky, a bright, yet light value mix of cobalt turquoise and white. The color of the sky determines the light source and therefore affects all the other color mixes on the canvas. If the sky is gray, there are no blues being reflected off of the landforms in the shadows below; nor are there warm yellows reflecting off of the landforms in the sunlit areas since the sun is also blocked. Therefore only grayed variations of all the colors are possible if I am limiting myself to reality which, of course, I am not. Reality is only a starting point. When the sky is blue, the shadow areas will reflect a lovely blue variation of the local color and the sunlit areas will reflect white or yellows variations of local color. As the sun sets and the sky becomes more purple with oranges reflecting off of the clouds, the same colors appear in the shadows and lit areas of the landscape.

I remember the first winter after discovering alizarin crimson. It was the early 70's. Winter no longer appeared gray, white, black and brown with a blue sky overhead. Everywhere I looked I saw crimson and purple brambles, hillsides of lavenders and pinks. My eyes, having awakened to the crimsons of the leafless trees and bushes, became aware of the bright blues in shadows cast upon snow next to the sunlit yellows and oranges. Once again, painting is awakening me to new colors and nuances of color that have surrounded me all my life without my taking notice.
