Simple question. I like the Ambiance-dark theme found online, but I heavily dislike orange. I went in the theme files and modified the colour settings to green, but there is one little thing that I can't seem to find how to change: the separators for dropdown menu and tools. Here is a screenshot:

enter image description here

As you can see, these are pink (or light orange if you prefer). How do I change those colours?

Now, I haven't yet changed the hue of all the assets of the theme (only the close button, which can be seen on screenshot. I'd like to know if these colours (menu/tool separators) are assets dependant.

A useful tool I use to customize gtk theme is gtk-theme-config. I for example like the default ambiance them but I set it to use a green scheme so it looks better with the gnome colors icon theme.

You can see here the greybird gtk theme wich has a blue scheme by default turned to purple and the gtk theme config at the bottom right corner.

Greybird gtk them wich has a blue scheme by default.

For install it in Saucy:

sudo apt-get install gtk-theme-config

For previous ubuntu releases:

sudo add-apt-repository ppa:shimmerproject/ppa
sudo apt-get update
sudo apt-get install gtk-theme-config
