Marshall's advice can also be applied to when the OP wants to pass multiple arg hashes they can be passed as refs and looped over (avoiding the nasty splitting of args!):

#!usr/bin/perl -w
## shamelessly copied from Marshall

use strict;
use Data::Dumpe qw/Dumper/;

## pass two anon hash refs to the sub
Some_subroutine(

            { 'NAME'   => 'name222',
             'COLOR'  => 'yellow',
             'SIZE'   => 'big',
            },

            { 'NAME'   => 'name444',
             'COLOR'  => 'yellow444',
             'SIZE'   => 'big444',
            },

               );

sub Some_subroutine
{
  ## collect the refs passed to the sub
  my @list = @_;
  ## just to see what we got
  print Dumper \@list;
  ## loop through each ref passed and process as before
  for my $ref (@list){
    foreach my $key (keys %$ref)
    {
       print "key $key \tvalue is $ref->{$key}\n";  
    }
  }
}
