Taskbar color

Hello:

A week or so ago, my taskbar color changed, and I do not know why. I had turned off the wavy white/light blue bands on the blue background on the desktop and on the taskbar (and I have, of course, forgotten how I did that). But the color change did not happen at that time, but rather a few days or a week later.

Where can I set the color and the pattern of the default desktop and of the taskbar.

Thanks for your help!

Valtonray, that was exactly what I meant. Thank you very much. I now have a wonderful landscape background on my main monitor. Will get some to my other two monitors too.

Best regards,
