index file overrides background color

I’m designing a website and ran into a issue. There is a section of code from (index) that is overriding certain properties from the sytle.css

a, a:visited, .page-template-front .hfeed-more .hentry .entry-title a:hover, .entry-title a, .entry-title a:visited {
    color: #a5a5a5;
}

So if I try to change the color of the hover, entry-title etc it will get overridden with the color hex code from the section above. How can I delete that section or otherwise take out the objects I do not want effected by it?
