besides the correct style setting.
If this is a link you are trying to change the color on you have for example:
General CSS Properties
body
color: #000000; background: #ffffff; font-family: Trebuchet MS, Verdana, Arial, Helvetica, sans-serif; font-size: 10pt;
Special Link Properties
Unvisited Link color: #336699; background: none;
Visited Link color: #336699; background: none;
Active Link color: #336699; background: none;
Hover Link
Pay attention to the unvisited,visited and active link settings.
Other than that I guess we need more specific information on what you are trying to change. Maybe a screen shot since we don't have a url.
