Been doing this since 10.1 and I make the screen really bright and ugly so I don't stay in it longer then absolutely necessary :-)

You could probably go to a Finder window's View Options and set the background colour, for "all windows", to something obviously unusual [for you]. For me, that would be RGB 0/255/0 -- not that I'd run Finder as root.

I use the window background colours as my own sort of Label system, though, which is why it frustrates me that Finder keeps defaulting to "All windows" when I try to change View Options for a window.

Example: for a folder that holds original files, which I wouldn't want to change, nor lose, nor fail to notice, I make that folder's background bright red.

For folders that contain finished products, ready to be delivered, backed up, etc., I turn the folder background green.

You get the idea; I won't go into the rest of my color code, except to say that I use subtle shades, which is something I can't do with ordinary file Labels. Example: some files are originals, or early drafts, and I *probably* don't want to delete or change them -- I make that folder background red, but not bright red. Darker red means less crucial, in my scheme.

I very much appreciate that feature and use it often. When I set up another's Mac, I change the background windows of their admin user accounts to red [all windows], to help them realize they shouldn't be doing ordinary work when logged in as admin. I also change the desktop background to a huge warning sign.
