I just downloaded the hemisu theme for Emacs which works very nicely. One flipside of the theme is that the file-name shows up in very lightly colored letters, and so becomes difficult to read. This is a problem when several file buffers are open. Here is a screen-shot
To prevent such a thing for happening for any such themes in future, can I have all file-nams/buffer names be on a black background with with say a pink foreground, irrespective of which color-theme is active?
