[Theme: twenty eleven] Link color problem

Yes – I am working on a child theme based on twenty eleven.

I am having problems with link color. I see how to change it in the “settings” section and that all works fine.

There are places I would like to override that default link color. I have already done it in the navbar menu via the #access css section.

I also want to have post titles on the main page display in different color. These are links when displayed on the main “blog” page, and seem to only pick up the global color set for links.

I have modified the css to read:
.entry-title,
.entry-title a {
color: #FFFFFF;
text-decoration: none;}

I actually thought this was working for a moment, but then the page defaulted to the global link color.

Using “Firebug” is shows my css, but also indicates that the attribute I specify has been overridden by the theme default value for links.

Site is not published yet so I cannot provide a link. Any help would be appreciated.
