title: impresspages color picker incorrect color code
body: <p>I have been struggling to get default color picker work. When I add a new color field ( new \Ip\Form\Field\Color) on form page then after selecting color from drop down I get error "incorrect color code". And when I checked value returned is something like this "hsv(0, 25%, 34%)".</p>
  
  <p>After checking in Core files, Color Form field file then I found following function which is validating it. </p>
  
  <pre><code>public function validate($values, $valueKey, $environment)
  {
      if (preg_match('/^#([a-f]|[A-F]|[0-9]){3}(([a-f]|[A-F]|[0-9]){3})?$\b/', $values[$valueKey])) {
          return parent::validate($values, $valueKey, $environment);
      } else {
          if ($environment == \Ip\Form::ENVIRONMENT_ADMIN) {
              return __('Incorrect color code', 'Ip-admin', false);
          } else {
              return __('Incorrect color code', 'Ip', false);
          }
      }
  }
  </code></pre>
  
  <p>Can you please check and let me know why it is generating HSV code for color "hsv(0, 25%, 34%)"</p>
  
  <p>Thanks in advance.</p>
