    $facilitiessql="select * from ".TABLE_ADM_FACILITIES;
    $facilitiesrun=mysql_query($facilitiessql);
    while($facilitiesfetch=mysql_fetch_array($facilitiesrun))
    {
      $i = 0;
      $styleCode = '';
      if(isset($arrColorCode[$i]))
        $styleCode = "style='background-color:$arrColorCode[$i]'";
      ?>
      <div class="wpb_column vc_column_container vc_col-sm-3" <?php echo $styleCode; ?>>

          if(isset($arrColorCode[$i]))
            $styleCode = "style='background-color:$arrColorCode[$i]'";
        ?>
        <div class="vc_column-inner vc_custom_1458192848305" <?php echo $styleCode; ?>>

You can create an array of colors $colors with the colors you want. After in your while iteration you can get one color value fron that array and apply on div style (In my example I put it on color property but it can go on background-color or another property).

<div class="vc_row wpb_row vc_inner vc_row-fluid">
    <?php
        // Your php code here
        $colors = array('#112233', '#445566', '#778899');
        $cIndex = 0;
        while($facilitiesfetch=mysql_fetch_array($facilitiesrun))
        {
            $color = $colors[$cIndex++ % count($colors)];
    ?>
    <div class="wpb_column vc_column_container vc_col-sm-3" style="color: <?php echo $color; ?>;">
      <!-- The rest of your html here -->
    </div>
    <?php } ?>
</div>
