Hi,

you can't. Some theme (e.g. the ones based on the pixmap engine)
can use images and totally ignore the background colors you set.
E17gtk seems to be pixmap based:

https://github.com/tsujan/E17gtk/blob/master/gtk-2.0/gtkrc#L99

You can disable the engine and style from scratch, but this will
quickly end up in creating a new theme.

If you want full control over something just use a canvas. Don't
try to bend the theme to do what they are not supposed to do, e.g.
change the background image to something "redish" because you set
a red background.

Ciao.
