You can use [calc] tags, since they remember values within a page.
Here's one way, for example:

 <table>

    [comment] Set the initial value to 1 [/comment]
    [calc] $c = 1; ''; [/calc]

    [tag each products]
       [comment] Toggle the value between 1 and -1 for each row,
                 output a color accordingly: [/comment]
       <tr bgcolor="#[calc]
                        $c *= -1;
                        ($c > 0) ? 'cccccc' : 'ffffcc';
                     [/calc]">
          <td>[loop-code]</td>
       </tr>
    [/tag]
 </table>
