Try to implement the following code for class 'XLite\Module\Pmall\PmallSkin\Main':

    const COLOR_SCHEME_STANDARD = 'Standard';
    public static function getLayoutColors()
    {
        return array(
            static::COLOR_SCHEME_STANDARD => \XLite\Core\Translation::lbl('Pmall'),
        );
    }
