This is a sunrise in the desert. The sun is orange. Some dunes are lit from the sunlight. Some are still in the shadow. That colors them into pink - violet - burgundy. Looking away from the sun you see the yellow dunes. The sky is changing color from dark blue to blue to light blue. The lines show us the female forms of the dunes.The nights are cold in the desert, so are the colors in the painting, but we are getting the glimpse of the cruel desert heat.
