I think you have to use CSS -- unfortunately that is some work and I can
not provide an example yet. See

de-background-color
Thanks. I've tried the CSS approach: that is, create a custom
GtkCssProvider and feed it a suitable snippet of CSS inline. This
works to change the background color OK. But step 2 is to revert the
background color to normal once the alert is over, and I couldn't
figure that out, because I couldn't find a way of determining what
"normal" is.
There's an API "on the books" to get the original background color
(which in principle would allow you to save it, and re-apply it
later) but it doesn't work in current gtk 3 (now it always just
gives you an all-zero GdkRGBA).
I've studied the doc for gtk_widget_override_background_color(), and
in the code I posted I was trying to implement the suggestion there
to "use Cairo to draw a specific color, regardless of the CSS
style," in the hope that this would revert itself automatically the
next time a selection had to be drawn. But at this point I don't
know if that would work since I can't get the background to change
in the first place, using cairo plus gtk_render_background().
