But if translucency is supposed to help differentiate the frontmost layers of system components, surely the notifications behind it should be opaque.
Nevertheless, the rest of the system behaves as though the foreground window is comprised of panes of glass, and the background windows are made of solid plastic. Often, this means background windows actually have better contrast than windows in the foreground. If the window control widgets were in full colour instead of grey, you would be forgiven for assuming this is just what the app looks like all the time.
Some other apps exhibit reduced contrast when they are in the background. But because the sidebar is often a critical interface element, compromising its legibility in foreground windows means going to more extreme lengths of illegibility for background windows. When Mail is in the background, the text labels and icons in the toolbar and sidebar become a mid-grey that, on the light grey background, is difficult to read.
This makes it more obviously an inactive window, but it is so bright that it clashes with the active window and makes it hard to quickly see what is in the foreground:. This is not directly because there are translucent elements in foreground windows, but the wildly insufficient contrast in background windows is necessary because foreground windows in Big Sur are already lower-contrast — because of their translucent elements.
There is a way to switch all of this off: in System Preferences, under Accessibility and then Display, you can tick the Reduce Transparency box. This makes everything opaque — though, unfortunately, it is indiscriminate, and I think the Dock works just fine as a translucent smear — but foreground and background windows in Big Sur are still similarly bright.
You can also select Increase Contrast if you want a black border around interactive elements. The smeared background of a toolbar looks worse in screenshots than it does in use. But I think this effect works far better in iOS than on the Mac. The translucent glass effect was adapted from iOS 7, introduced the year prior to Yosemite. Compared to the Mac, iOS devices have strict rules about where application windows will be. On an iPhone, an app is always running full-screen; on an iPad, there are more options, including apps that float over others.
But only a handful of system-level processes — Notification Centre, Control Centre, Spotlight, and, until recently, Siri — blur the contents of windows behind. Translucency in apps only affects the contents of that app: toolbars give an impression of what lays beyond the current scroll view; contextual menus sit in a layer overtop the app area. Translucency here adds depth to an interface with a singular context. MacOS is messier than this. It encourages the use of multiple windows stacked haphazardly.
Making elements of the foreground window translucent provides no new information. On the contrary, it creates confusion within itself and for background windows that are necessarily opaque.

I believe what you are looking for is rgba Here is a snippet explination from a book I have The Alpha channel Alpha for short is the measure of the transparency of a color—as opposed to the opacity property, which is the measure of the trans- parency of an element.
