=head1 SYNOPSIS

  ; .replyrc
  [Colors]
  error   = bright red
  warning = bright yellow
  result  = bright green

=head1 DESCRIPTION

This plugin adds coloring to the results when they are printed to the screen.
By default, errors are C<red>, warnings are C<yellow>, and normal results are
C<green>, although this can be overridden through configuration as shown in the
synopsis. L<Term::ANSIColor> is used to generate the colors, so any value that
is accepted by that module is a valid value for the C<error>, C<warning>, and
C<result> options.
