Пару часов назад все сделал и верстал визуализацию, если понадобится кому-то:

$TPcolorsList = array();
$arResult['CATALOG_TP_COLOR'] = array();
$arSelect = array("IBLOCK_ID", "ID", "NAME", "DETAIL_PAGE_URL", "QUANTITY", "PROPERTY_*");
$arFilter = Array("IBLOCK_ID" => 5, "ID" => $arResult['PROPERTIES']['CATALOG_TP_COLOR']['VALUE']);

$colors = HighloadBlockTable::getList(array("filter" => array('TABLE_NAME' => "bxready_color")))->fetch();
$restp = CIBlockElement::GetList(array(), $arFilter, false, array("nPageSize" => 10), $arSelect);
while ($ob = $restp->GetNextElement()) {
    $arFields = $ob->GetFields();
    $TPcolorsList[$arFields['ID']]['NAME'] = $arFields['NAME'];
    $TPcolorsList[$arFields['ID']]['DETAIL_PAGE_URL'] = $arFields['DETAIL_PAGE_URL'];
    $TPcolorsList[$arFields['ID']]['ID'] = $arFields['ID'];
    $TPcolorsList[$arFields['ID']]['QUANTITY'] = $arFields['QUANTITY'];
    $arProps = $ob->GetProperties();
    if (isset($colors['ID'])) {
        $entity = HighloadBlockTable::compileEntity($colors);
        $entity_data_class = $entity->getDataClass();
        $res = $entity_data_class::getList(array('filter' => ['=UF_XML_ID' => $arProps['COLOR']['VALUE']]));
        while ($item = $res->fetch()) {
            $TPcolorsList[$arFields['ID']]['COLOR'] = $item['UF_NAME'];
        }
    }
}
if (count($TPcolorsList) > 0) {
    $arResult['CATALOG_TP_COLOR'] = $TPcolorsList;
}
unset($colors);
unset($TPcolorsList);
unset($arSelect);
unset($arFilter);
unset($restp);
