This is related to https://askubuntu.com/questions/78653/how-can-i-change-the-color-of-this-part-of-nautilus-for-my-ambiance-theme-modifi/79006#79006, which has just been solved. Now I have a new issue.
As shown below, the text color for the sidebar does not want to stay white unless it is selected. It did earlier, but now it's not and I'm not sure why.
How can I force that text to stay white in the theme files? (See the linked question above for a reference as to what changes I made; everything else is the same as regular Ambiance.)
Note: it'd be great if the white used for the sidebar text color was the same as the default white used for the active window titlebar text; #ffffff
might be a little too bright, and I'm trying to stay close to the original look of Ambiance.
