Required when required not selected

The colorpicker cck field is for some reason always required even though the required button is checked in the cck preferences. I've fixed this by commenting out the following code:

if ($item['value'] !== '#' && !preg_match('/^#(?:(?:[a-f\d]{3}){1,2})$/i', $item['value'])) {
//form_set_error($error_element, "'". check_plain($item['value']) ."'". t(' is not a valid hex color'));
}
