You don't state it explicitly, but I assume you want to change
the background color per buffer, perhaps per window.

For a long time it was only possible to set the whole frame's
(an Emacs frame is what the window manager considers a "window")
background color. This has changed since Emacs 24-ish, see for
example

(this seems to be exactly what you're looking for).
