So it looks like you globally changed the h1 header HTML and the user profile name just happens to use that tag.

The code is in MediaWiki:Wikia.css...

...and looks like this: h1{ color:rgba(100, 50, 255, .8); }

If you want to affect only the user profile name (all names on your wiki) and not h1 in general, you would want to use CSS like this:

div.masthead-info > hgroup > h1 { color:rgba(255, 127, 0, .8); }
