I've put together an icon/theme combination for my Ubuntu 14.04 + GNOME. Unfortunately, my color settings for contextual menu are applied for most applications, but not for Chrome - when I right-click on a website in Chrome, the menu that shows up has different highlight and background colors than what I've designed (the ones that do show up are quite ugly!). The contextual menu in Nautilus looks fine, though.
How do I fix that? Is there a separate set of styles for other kinds of contextual menus?
