Need help with Cinnamon desktop

I'm trying to customize my Cinnamon desktop in Ubuntu and running into some difficulties. First off, I want to modify the background to a solid color, not an image. It appears I can set solid (or gradient) colors on the settings tab (see image), but I can't seem to remove the background image. I've been able to modify the cinnamon.css file, but the desktop background does not appear to be in there.

Attached is a slice of my desktop, open to the Backgrounds setting. Notice there are no images listed. Not even the one currently displayed; not sure why. In any case, I just want to get rid of that intense turquoise background image and just put a solid color. How?

"The solutions and answers provided on Experts Exchange have been extremely helpful to me over the last few years. I wear a lot of hats - Developer, Database Administrator, Help Desk, etc., so I know a lot of things but not a lot about one thing. Experts Exchange gives me answers from people who do know a lot about one thing, in a easy to use platform." -Todd S.

Alright, I found the answer:

System Settings > Backgrounds > Settings > Picture Aspect. I set that to 'No Picture', and it worked. Hmmm - a bit obscure, but oh well.
