+=head1 NAME
+
+TAP::Formatter::Color - Run Perl test scripts with color
+
+=head1 VERSION
+
+Version 3.12
+
+=cut
+
+$VERSION = '3.12';
+
+=head1 DESCRIPTION
+
+Note that this harness is I<experimental>.  You may not like the colors I've
+chosen and I haven't yet provided an easy way to override them.
+
+This test harness is the same as L<TAP::Harness>, but test results are output
+in color.  Passing tests are printed in green.  Failing tests are in red.
+Skipped tests are blue on a white background and TODO tests are printed in
+white.
+
+If L<Term::ANSIColor> cannot be found (or L<Win32::Console> if running
+under Windows) tests will be run without color.
+
+=head1 SYNOPSIS
+
+ use TAP::Formatter::Color;
+ my $harness = TAP::Formatter::Color->new( \%args );
+ $harness->runtests(@tests);
+
+=head1 METHODS
+
+=head2 Class Methods
+
+=head3 C<new>
+
+The constructor returns a new C<TAP::Formatter::Color> object. If
+L<Term::ANSIColor> is not installed, returns undef.
+

+# new() implementation supplied by TAP::Object

+        return;    # abort object construction

+
+  Test::Formatter::Color->can_color()
+
+Returns a boolean indicating whether or not this module can actually
+generate colored output. This will be false if it could not load the
+modules needed for the current platform.
