you can modify bits of the CSS from your code like this (taken from
Bluefish code bftextview.c):
GString *str = g_string_new("");
GtkStyleContext *stc;
GtkCssProvider *cssp = gtk_css_provider_new();
str = g_string_append_printf(str, "GtkTextView.view {background-color:
%s;}", colors);
gtk_css_provider_load_from_data(cssp, str->str, -1, NULL);
stc = gtk_widget_get_style_context(GTK_WIDGET(mywidget));
gtk_style_context_add_provider(stc, GTK_STYLE_PROVIDER(cssp),
GTK_STYLE_PROVIDER_PRIORITY_APPLICATION);

Olivier

Quite often widget colors are just a question of style but sometimes
this is not the case. I can think of medical applications, for example,
where colors can be critical.
In my case, I have a chemical periodic table made with GTK buttons, each
one representing a chemical element, with its default color. Users can
change these chemical element default colors directly from the interface

You have to use a CSS file (a working example in my code) and import from
code
to override the gtk3 theme that you are using on your distribution.
Cheers,
Giuseppe.
I had a similar problem and it seems that even with Priority = Application
the default theme is overriding "override_background_color()". I would
like to know if this is a bug as I wasted several hours trying to find the
work around and ended up having to use the css method with the applicable
config from the default theme which seems a little excessive when a 1
liner in code should be possible.

button background color in gtk3
Friends,
I am putting gtkbuttons inside a grid with modify_bg. I am getting an
odd case that when the window is focused, all buttons are showing white,
not what suggested by modify_bg. The same structure was working fine in
gtk2 (while I was using table instead of grid).

I have seen that the gtk_widget_modify_bg is deprecated in gtk 3 so I
tried the suggested method with gtk_widget_override_background_color but
there it seems that declaration of GdkColor colorRed2 = {0x, 65535,
29555, 24158} has changed to something like GdkRGBA.

GdkRGBA colorRed = {1,0,0,1};
