=head1 NAME

App::AltSQL::View::Plugin::Color - Colorize the output in a context sensitive way

=head1 DESCRIPTION

This uses the L<App::AltSQL> configuration file for customizing how things are colored.  The default configuration is:

  header_text => {
    default => 'red',
  },
  cell_text => {
    is_null => 'blue',
    is_primary_key => 'bold',
    is_number => 'yellow',
  }

The values are passed to L<Term::ANSIColor> so any supported color may be used.
