I recently received help getting the account folder "New Mail" color changed from default blue to red (thank you). I suspect that my next question may be more difficult if not impossible but... All of the actual account folders now display red when there is new mail, but the subfolders under Local Folders still display the default blue. I have looked around but, due to my ignorance of CSS in Thunderbird I can't find any clues. Is there a way to change the default blue for new mail in the Local Folders subfolders to some other color?
