Why should this be GTK only? Why not copy all the prefs on all platforms? There
might be a good reason not to do this although I can't think of it off the top
of my head.

It's only GTK that uses the renderer_prefs->color values from what I read the
code:
http://108.166.104.54/source/xref/chromium/src/content/public/common/renderer...,
Also selection color works fine without the changes here on win and mac.

+    // Copy selection color and caret blink rate prefs from embedder, otherwise
+    // things don't work on gtk.
+    content::RendererPreferences* embedder_renderer_prefs =
+        web_contents()->GetMutableRendererPrefs();
+    content::RendererPreferences* guest_renderer_prefs =
+        guest_web_contents->GetMutableRendererPrefs();
+
+    guest_renderer_prefs->active_selection_bg_color =
+        embedder_renderer_prefs->active_selection_bg_color;
+    guest_renderer_prefs->active_selection_fg_color =
+        embedder_renderer_prefs->active_selection_fg_color;
+    guest_renderer_prefs->inactive_selection_bg_color =
+        embedder_renderer_prefs->inactive_selection_bg_color;
+    guest_renderer_prefs->inactive_selection_fg_color =
+        embedder_renderer_prefs->inactive_selection_fg_color;
+
+    guest_renderer_prefs->caret_blink_interval =
+        embedder_renderer_prefs->caret_blink_interval;

     AddGuest(instance_id, guest, frame_id);
     guest_web_contents->SetDelegate(guest);
   } else {
