Very rarely do I use orange in any of my watercolors even though I love orange. I even have orange fingernail polish. I decided that since this was a losing painting anyway and that I could just do whatever I wanted to it. Otherwise, it would go into file 13. When you see these things growing, they are in an undesirable piece of ground or tree that you wouldn't really want to touch with all of the mold, mildew and yucky stuff round them. So, I painted yucky stuff. It works now! I think!
