Forum:Changing Infobox Text color

On the Warehouse 13 Artifact Database Wiki, we have a slight issue with the text color in the infoboxes. We have a white backround with light grey text, making it near impossible to read. I've scouered the internet, but I can't find anyway to switch the text to a darker color. Any help?

 * Maybe put

.WikiaArticle .infobox { color: #000000; }
 * in your Mediawiki:Wikia.css page? Or whatever colour you want-- Category:Acer4666 20:03, October 9, 2012 (UTC)

I don't know how to get access to the MediaWIki:Wikia.css page...I admit that I am a noob at this...
