I would find it more "logical" to have:

- the whole of the error messages in red (such as what I have with Zsh
  where /dev/stdout and /dev/stderr are respectively in white-on-black
  and in red-on-black, see http://screencast.com/t/eteXGMDvYajm), and

- the clickable links (for error navigation) outstanding in different
  colors (such as the results of a Grep, with the `compilation-info' +
  `compilation-line-number' faces);
  see http://screencast.com/t/0lXAPhY72.

I find that very hard to parse (understand: read), because of the mix of
colors. But, yes, that can be only me with my point of view...

Best regards,
