CSS Content Text-Color chance

Hi,

I'm again:-)

How do I chance the text-Color of my content.
see the attachment:

You can change this in template parameters.

ok, I know.

But I see that is a differenz between Firefox and InternetExplorer.
In the InternetExplorer the chance of the color is ok but
in the Firefox seam a differenz color?

InternetExplorer:


Firefox:


I think that in index.php are the solution:
<style type="text/css">
<!--
<?php require(dirname(__FILE__).DS.'css/template_css.php'); ?>
-->
</style>
<!--[if IE]>
<style type="text/css">
<?php require(dirname(__FILE__).DS.'css/template_css.php'); ?>
</style>
<![endif]-->

What do you think of this code?

You are loading template inline style twice for IE?
