I looked everywhere online and I couldn't find a thing. For example I have a wallpaper centered and the backdrop is black but I want to change it to other colors such as white. This was a piece of cake on win7.
Because you used it as an example of a wider query. To answer specifically, set your background to solid colour, choose your colour, then reselect picture.
Right click on the desktop and choose personalize from the pop-up menu. If you have an unactivated copy of Windows the personalization options are limited though.
I did, I just didn't specifically tell you how to do that one precise thing you asked about. I pointed you toward the customization settings. There is a way to change the background colour and a myriad of other personalization options if you can find them

That worked! Only problem is I don't see white but I do remember what other threads said about that. Sucks that we have to use a white image or that cmd path.
