There are many questions in this site on changing the background color of quoted text, but I am bewildered and disheartened by the huge proliferation of different ways to do this, each using a different additional package. I can't believe that such a common and conceptually simple task doesn't have one basic, canonical solution. (This solution may be inadequate for specific situations, of course, but only then I would consider bringing in speciallized tools.)

Basically, I'm looking for something analogous in appearance to

...or

```
this effect (but without the change of font or foreground color, just the background color change)

```

...or preferably somewhere in-between, namely, *the simple color change of the latter, but without the change of font*.

Doesn't "bare LaTeX" provide a way to do this?
