I have painted this same subject before. Now tried it with a twist, by painting it over gesso. The colors shine even more over gesso. The technique will need getting used to.
One smooth pink mountain; another one quite rugged and brown right next to it. Grass of unrecognizable colors, and fan palms growing in the canyon. The landscape is far from conventional at Palm Springs, CA. Its unsettling to grasp and to paint as well.
