Colors for M-x shell

[Sebastien Vauban <sva-news-D0wtAvR13HarG/iDocfnWg@public.gmane.org>]

Hello,

I'd like to change the color for the directories, executables, etc for
the shell mode.

Though, I don't see (for example) where the "bold blue2" gets defined
for the directories.

See http://screencast.com/t/y4hUcRquPec.

Can you give me a hint?

Best regards,
  Seb

PS- It'd be great to have just one definition that'd be used for both
Shell mode and the highlighting of the completions (when pressing
`C-x d TAB TAB') when one does have:

--8<---------------cut here---------------start------------->8---
  ;; provide the same facility of `ls --color' inside Emacs
  (autoload 'dircolors "dircolors" nil t)
  (add-hook 'completion-list-mode-hook 'dircolors))
--8<---------------cut here---------------end--------------->8---
