  package Form::Factory::Feature::Control::Color;
our $VERSION = '0.002';


  use Moose;

  with qw( Form::Factory::Feature Form::Factory::Feature::Role::Control );

  has recognized_colors => (
      is        => 'ro',
      isa       => 'ArrayRef[Str]',
      required  => 1,
      default   => sub { [ qw( red orange yellow green blue purple black white ) ] },
  );

  sub check_control {
      my ($self, $control) = @_;

      die "color feature is only for scalar valued controls"
          unless $control->does('Form::Factory::Control::Role::ScalarValue');
  }

  sub check_value {
      my $self  = shift;
      my $value = $self->control->current_value;

      $self->control_error('the %s does not look like a color')
          unless grep { $value eq $_ } @{ $self->recognized_colors };
  }

And then used in an action via:

  package MyApp::Action::Foo;
our $VERSION = '0.002';


  use Form::Factory::Processor;

  has_control favorite_primary_color => (
      control  => 'select_one',
      options  => {
          available_choices => [
              map { Form::Factory::Control::Choice->new($_, ucfirst $_) }
                qw( red yellow blue )
          ],
      },
      features => {
          color => {
              recognized_colors => [ qw( red yellow blue ) ],
          },
      },
  );
