The only thing that actually gets a color set is the option menu background when the mouse is over it, and the optionmenu's width. Thanks, -Peter Oh, sorry. Rereading the original post, I've since changed the original module that I was using. The Tk widget code now looks like this (mostly lifted from Mastering Perl/Tk): 
package LabelOption;

use Tk::widgets qw /Optionmenu/;
use base qw/Tk::Frame/;
use strict;

Construct Tk::Widget 'LabelOption';

sub ClassInit
  {
    my($class, $mw) = @_;
    $class->SUPER::ClassInit($mw);
  }

sub Populate
  {
    my($self, $args) = @_;

    $self->SUPER::Populate($args);

    my($o) = $self->Optionmenu->pack();

    $self->Advertise('optionmenu' => $o);
    $self->ConfigSpecs('DEFAULT'  => [$o]);
    $self->Delegates('DEFAULT'    => $o);
  }
