Thanks ikegami, your idea gets me closer however, I get no output. Looks like I'm still doing something incorrect. Below is my actual test script: 
use warnings;
use strict;

my $COLOR=2;
my $hm="";
my $ht="";

my %h1 = (
                   "1" => "blue"
);

my %h2 = (
                   "2" => "green"
);

if ( $COLOR == 1 ) {
     $ht=\%h1;
}
elsif ( $COLOR == 2 ) {
     $ht=\%h2;
}

sub geth {

      while ((my $key, my $value) = each(%$ht)) {
          if ( $key == $COLOR ) {
              $hm=$value;
          }
      }
         print "$hm\n";
}
