In RedHat it is /etc/DIR_COLORS, in GNU fileutils it is src/dircolors.hin.

Unless that I could use ls --color=auto.


At all.
There is command in fileutils that parse dircolors.hin and returns LS_COLORS
setup script. Many distributions use it. When therminal is dumb, dircolors
sets this environment variable to ''. But in ls if LS_COLORS='' color
indicators take their default value. And ls colors text as default.


The only check on this way in current time is check for isatty

   /* Using --color with no argument is equivalent to using
       --color=always.  */
         i = color_always;

          print_with_color = (i == color_always

                              || (i == color_if_tty

                                  && isatty (STDOUT_FILENO)));

I suppose, you must add

 /* Using --color with no argument is equivalent to using
       --color=always.  */
         i = color_always;

          print_with_color = (i == color_always

                              || (i == color_if_tty

                                  && isatty (STDOUT_FILENO))
                                  &&(*getenv("LS_COLORS") != 0 ));

Thanks for attention.
