you have to modify background colors & text color used in alerts.css belonging to active theme of the forum

There is my alerts wrapper class in alerts.css. Alerts.css is located in your Themes and templetes->your theme name.
Change the background to any hex value

ie background: #ebebeb;
I have done this to my own alerts as I wanted a black background.
