dynamic rgb value not working

I have the following code:

echo '<td bgcolor="rgb(255, '.(255-$count_ac).','.(255-$count_ac).')">&nbsp;</td>';

----- $count_ac is a simple variable that house a number -----

after processing, it presents properly like the following:

<td bgcolor="rgb(255, 248,248)">

But the color displayed is a dark green -- it should be light red (pink)

As W3C says "The bgcolor attribute of <td> is not supported in HTML 4.01 Strict / XHTML 1.0 Strict DTD." so check your DOCTYPE definition.

You may still be able to get away with using something like this (obviously untested code)...  But the correct way to handle this is to use style sheets.

<?php
$r  = dechex(255);
$g  = dechex(255 - $count_ac);
$b  = dechex(255 - $count_ac);
$bg = '#' . $r . $g . $b;
$st = 'span style="background-color:' $bg . '"';
$td = "<td $st>&nbsp;</td>";
echo $td;

Why in the world would you use an obsolete property like bgcolor instead of styling it with:
echo '<td style="background-color:rgb(255,' . 255-$count_ac.','.255-$count_ac.')">&nbsp;</td>';

Then at least it would work consistently in virtually all browsers that have been manufactured in the last 10 years. Even as far back as IE4.  and everything in the future.
