Ok, well in that case you could have a Handler::Colors that has returns those 80 objects from its new() method (though I would probably call it something else, then, like init()):

package Handler::Colors;
use YAML qw(Load);  # or some other module to handle config-like files

#  set up a bunch of event handlers that
#  send email depending on colour

sub init {
  my $colors = Load('/color/config');
  my @handlers;
  while (my ($color,$email) = each %$colors) {
    @handlers = Handler::Colors->new(
       {
         color => $color,
         email => $email
       }
    );
  }
  return @handlers; #update: added this line!
}

# create handler object

sub new {
  my $class = shift;
  return bless { @_ },$class;
}

# check for my color and send email if found.

sub handle {
  my ($self,$event) = @_;
  if ($self->{color} eq $event->color()) {
     send_mail($self->{email});
  }
}

updated: added return @handlers line

update2: To clarify: this code plugs into the code in my post above, so you can have more of these classes for each different type of action you need to perform. All that's changed there is that the

  push @event_handlers,"Handler::$_";

line needs to be replaced by

  push @event_handlers,"Handler::$_"->init();
