I'm struggling to figure out how to inject colored output while running tests with prove: 

use Test::Utils::Dump;
use Test::Dirs; # sets up temporary scratch directories 
use Test;

use_ok('File');
my $f = File->new();
$f->path($Test::Dirs::scratch . 'test.txt');
d $f; # d sub is in Test::Utils::Dump

My Dump utility module looks like this: 
package Test::Utils::Dump;
use Term::ANSIColor qw(colored);

use strict;
use warnings;

use Data::Dumper qw(Dumper);

# export the dump function
use Exporter qw(import);
our @EXPORT_OK = qw(d);

# dump the data passed in
sub d {
    my $data = shift;
    print colored ['green'], "\nDumping data...\n";
    # print the data and the caller
    my $caller_line = "Dump from: " . (caller(0))[1]
      . ' line: ' . (caller(0))[2] . "\n";

    print colored(['green'], "\n" . $caller_line);
    print Dumper($data);
    print $caller_line;
}

When I run the test with prove, however, the output from the debug code is still in black and white. Prove is outputting some color so I know that's working. For example, "All tests successful" shows up in green. Addendum: Also, I can inject color directly into the output if I do print colored right into the test file itself. But this confuses prove unless I print to STDERR.
