Thanks!

How can I change the text-color? My site is running on a light background, but this module will have a dark background. So i cannot use the styling from my template css-file.

There is no background color in the module. IT is your header background showing. If you want to add some background color, add thi to the css style in the module php file

#newsscrollerjp {
height:<?php echo $height; ?>px;
border: 1px solid #999;width:100%;overflow:hidden;
}

to this add
background:#ffffff;

for white background and it will become like this

#newsscrollerjp {
height:<?php echo $height; ?>px;
border: 1px solid #999;width:100%;overflow:hidden;
background:#ffffff;
}

I meant:

It's not the background color i want to change, but the text-color for linked title, date an intro text. I want to keep the the dark background, but i can't change it in my template css file, because it won't work on my white pages.
