Firebug add-on ... css.php ... upgrade script.

** Left my hints. Google around or search on the community :)

Thank you for the hints, I went to views}default} css.php and changed one color value. It worked.

Best not to change core files.  Put this in a plugin so you don't lose the modifications when you upgrade Elgg.

Here is an idea that is more of what Evan and Shouvik are saying and merging both.

Find a basic theme, edit that all you want, it will overide the core view with no changes to the core itself.

advantage = learn how elgg works at the plugin level

Wonderful, thanks a lot guys
