According to adduser(1):
  adduser will copy files from SKEL into the home directory

According to adduser.conf(5):
  SKEL is the directory from which skeletal user configuration files are copied.
  Defaults to /etc/skel

/etc/skel/.bashrc contains:
  # enable color support of ls and also add handy aliases
  if [ -x /usr/bin/dircolors ]; then
    test -r ~/.dircolors && eval "$(dircolors -b ~/.dircolors)" ||
eval "$(dircolors -b)"

The output of 'dircolors -b' looks like:
  LS_COLORS='<preconfigured_values>'; export LS_COLORS

The above is how Debian sets up the default value of LS_COLORS.

The values in use, if any, can be seen by
  echo $LS_COLORS

Personally I dislike the preconfigured values because they try
to color the output according to BOTH the type of file AND the
filename suffix, which creates a mess. Because the coloring
depends on whether or not the filename is matched.

I create a simpler ~/.dircolors which detects only the type of the file,
and use the above method to control the colors shown by 'ls'. I find it is
very useful for recognising hardlinks as well as good or bad symlinks
in the output of 'ls' command. It's not hard and gives a useful result.

I also configure 'mc' to use the same colors.
