The first 6 lines of your code are extremely hard to read so I rewrote them. You were mixing <?php and <? which isn't good practice and the style of for loop that you should use when switching between HTML and PHP has been changed, too. A lot of this is preference, though, so feel free to disagree or change it back.

<?
$result = dbclass::convert_array($res);
$rows = count($result);

for ($i = 0; $i < $rows; $i++) :
?>

<div id="Color" 
style="background-color:<? echo $result[$i][1];?>; width:32px; height:26px;" 
onclick="changeColor(<? echo $result[$i][1]; ?>)">
</div>

<? 
endfor;
?> 

function changeColor(newColor) {
    $('#changableColor').css('background-color', '#' + newColor);
}

$("#changableColor").css("backgroundColor","#colorCode");

---

$("#changableColor").css("background","#fff");

HERE is an example

There are a multitude of problems in your code. Firstly, inside your for loop you use an ID instead of a class, you should only use an ID once. Secondly, there are better ways to attach this. Please accept below and untested example, it should work, but will need some testing.

<?php
    $result = dbclass::convert_array($res); //retrieving colors here
    for($i = 0; $i < $rows; $i++) {
?>

<!--  Using class .color instead of ID -->
<div class="color" style="background-color:<?php echo $result[$i][1];?>; width:32px;  height:26px;">
</div>

<? } ?>

<div id="changableColor" style"background-color:#FFFFFF;"> </div>

<script type="text/javascript">
    $(document).ready(function(){
            // Attaching using a jQuery click function
        $(".color").click(function(){
                    // Using this operator to grab the background-color of the clicked item
            $(#changableColor).css("background-color",$(this).css("background-color"))
        });
    });
</script>
