CheckboxList vypisu v emailu pouze „Array“

Dobry den,
omlouvam se, ale nemohu prijit kde delam chybu. Pri odeslani formulare prijde pouze „Array“ misto vypisu co clovek vybral pomoci Checkboxu.

Tady je samotny presenter:

<?php
use Nette\Application\UI;
use Nette\Mail\Message;
use Nette\Environment;
use Nette\Mail\SendmailMailer;

class ColorsPresenter extends BasePresenter
{

	public function renderDefault()
	{

	}
	protected function createComponentColorsForm()
    {
      $form = new UI\Form;

      $colors = array(
      	'r' => 'red',
      	'g' => 'green',
      	'b' => 'blue'
      );
      $form->addCheckboxList('colors', '', $colors);

      $form->addText('name')
      ->getControlPrototype()->setClass('form-control');

      $form->addText('email')
      ->addRule(UI\Form::FILLED, 'Vyplňte prosím svůj e-mail.')
      ->addRule(UI\Form::EMAIL, 'Vyplňte prosím email ve správném tvaru.')
      ->getControlPrototype()->setClass('form-control');

      $form->addText('phone')
      ->getControlPrototype()->setClass('form-control');

      $form->addTextArea('note')
      ->setAttribute('rows', 6)
      ->getControlPrototype()->setClass('form-control');

      $form->addSubmit('submit', 'Odeslat')
      ->getControlPrototype()->setClass('btn')
      ->onClick = "javascript: if (typeof dataLayer === 'object') { dataLayer.push({event:'formColors',action:'submit'});}";

      $form->onSuccess[] = callback($this, 'ColorsFormSubmitted');
      return $form;
    }

    public function ColorsFormSubmitted(UI\Form $form)
    {
  		$values = $form->getValues();

  		$template = $this->createTemplate();
  		$template->setFile(__DIR__ . '/../templates/Emails/colors.latte');

  		$template->name = $values['name'];
  		$template->email = $values['email'];
  		$template->phone = $values['phone'];
  		$template->note = $values['note'];
  		$template->colors = $values['colors'];

  		$mail = new Message;
        foreach (Environment::getConfig()->formTo as $email) {
            $mail->addTo($email);
        }
        foreach (Environment::getConfig()->formBcc as $email) {
            $mail->addBcc($email);
        }
  		$mail->setFrom(Environment::getConfig()->formFrom)
  			->setSubject('form: Colors')
  			->setHtmlBody($template);

  		$mailer = new SendmailMailer;
  		$mailer->send($mail);

      $this->flashMessage('Děkujeme za odeslání formuláře.');
      $this->redirect('default');
    }
}
?>

A tady je vypis prijateho formulare:
