add background color to flash Created Jun 10, 2010

Hi, sorry for noob question.
How I can add background color?
It was:
<script type="text/javascript">
var so = new SWFObject("/flash/yes_HD_TV4.swf", "", "330", "330", "8", "#2d2d2d");
so.addParam("scale", "noscale");
so.addParam("menu", "false");
so.write("flashcontent");
</script>

after tool box:
<div id="hdtvsh"></div>
<script>
flashembed("hdtvsh", "/flash/yes_HD_TV4.swf" );
</script>
Please help me to add background color for the flash.
Thanks
