PHP/MYSQL What am i doing wrong

Question

So i need help with some stuff. In that photo bellow, "Kompanijos savininkas" should display "last name, name" of all users in the opened list. Every user_id has different color. So the name should be colored by the color which the code is. But i am doing something wrong because only color code is showing not the colored name. Here is the photo and codes which i changed. Help please.

// collect all the users for the company owner list
$q = new DBQuery;
$q->addTable('users','u');
$q->addTable('contacts','con');
$q->addQuery('user_id');
$q->addQuery('user_color');
$q->addQuery('CONCAT_WS(", ",contact_last_name,contact_first_name)'); 
$q->addOrder('contact_last_name');
$q->addWhere('u.user_contact = con.contact_id');
$owners = $q->loadHashList();

    <tr>
        <td align="right"><?php echo $AppUI->_('Kompanijos savininkas'); ?>:</td>
        <td>
    <?php
echo arraySelect($owners, 'company_owner', 'size="1" class="text" style="color:"$user_color"', 
                 ((@$obj->company_owner) ? $obj->company_owner : $AppUI->user_id));
    ?>
        </td>
    </tr>

 <?php
echo arraySelect($owners, 'company_owner', 'size="1" class="text" style="color:'.$user_color.';"', 
                 ((@$obj->company_owner) ? $obj->company_owner : $AppUI->user_id));
    ?>
