Try the following: 
$evilhash->{1} = {
  red   => 1,
  blue  => 2,
  green => 3,
};
my @colors = qw( red blue green );

print join("|", @{$evilhash->{1}}{@colors}), "\n";

The data structure you specified, the hash of hashes, would look like this: 
$evilhash = {
  '1' => {
    'blue' => 2,
    'green' => 3,
    'red' => 1
  }
};

(thank you Data::Dumper)

To get to that "1" hash, you have to explicitly dereference "1" with the "->" operator because "1" is a reference to an anonymous hash. I found this in perldsc.
