going crazy on setting the colors of my zip polygons via perl mapscript

Group,

I have found several samples of setting the color of a polygon based upon
class that I come up with this:

    $zip_expression =~ s/\|$//;
    my $class = new mapscript::classObj($layerObj);
    $class->setExpression("/$zip_expression/");
    $class->{styles}->{color}->{red} = 255;
    $class->{styles}->{color}->{green} = 153;
    $class->{styles}->{color}->{blue} = 153;
    $layerObj->draw($map, $img);

However - this is not working.  I am getting the right zip codes but no
matter what I do I can not get my mapscript to set the color based upon the
expression. When I was build the map file via perl I could set these just
fine but now I would like to use the perl->mapscript interface to do this.

What is wrong with the above snippet?

Thanks.
