Facebook comments colors

Hi all,

Today I updated my cutenews to version 1.5.0. It improved much and also the possibility with the Facebook comments is great. I've one problem with that facebook comments:

The color of the comments are #111111 or #222222, and my background is #000000. So it is very hard to read the comments. $matches[1]? Is it something with the appid? And how works that then?

$matches[1]

Thanks in advance
