scroll-bar-background feature:

Support the frame parameter scroll-bar-background. (Since emacs-25.3-mac-6.7) > If it is nil, which is the default, then the frame background color is used instead. Its color also affects the appearance of other GUI parts: the title bar, the tool bar, (the tab bar on macOS 10.12 and later), scroll bars, and popup menus become light (or dark) if the color is considered light (or dark, respectively). On macOS 10.12 and later, the title/tool/tab bars look slightly colored with the value of the `scroll-bar-background' frame parameter (or the frame background color) if the frame is focused and not in fullscreen.
