Hi Pete,
Thanks for your quick reply, I linked ~/.emacs_bash to ~/.bashrc but the
default color is still not changed. I read more about ~/.emacs_bash, it
seems to me emacs sends the content from this file to the interactive shell
upon starting. However, if I directly type "dircolors -b ~/.dircolors" in
emacs interactive shell, I got the following result:

LS_COLORS='';
export LS_COLORS

where as the same command typed in a regular system shell would yield the
desired LS_COLORS.

What could be the problem here?
Thanks,
Yuan
