when I do a 'ls --color' then directories will be displayed in BLUE
color.  Where can I modify this color configuration?

Thanks

Somewhere in /etc/most likely. On RH, they are specified in
/etc/DIR_COLORS.

DIR_COLORS(5)                                       DIR_COLORS(5)

NAME
       dir_colors - configuration file for dircolors(1)

DESCRIPTION
       The dir_colors file contains configuration information for
       the dircolors(1) program, which  in  turn  provides  color
       information  for  ls(1).   This  file is normally found in
       /etc, though users may maintain their own local copies  in
       their home directories as .dir_colors.

etc...

HTH, -sami.

That's for Linux not for HP-UX.  I could not find any man pages related
to dir_colors

It's not Linux, it's GNU fileutils. You did say you're using
GNU fileutils. Perhaps whoever installed them just didn't install
the man pages?

Try to see if you have the dircolors binary then create ~/.dir_colors by
dircolors -p > ~/.dir_colors (this has some documentation). See if it
works with "eval $(dircolors -b .dir_colors)".

Oh, and http://www.freebsd.org/cgi/man.cgi is a great resource for
man pages of various Unix(tm) and Unix-like operating systems.
