Twenty Twelve Link Color

Are you talking about the widget links?

nevermind it worked… but yeah the widget links have not changed.. how do I change those?

In your Child Theme or CSS Editor Plugin try this code:

.widget-area .widget a {
    color: #757575;
}

*Note
If your theme has a custom CSS Editor in it, you can also paste the code in there.

Never edit core CSS or PHP files, they’ll be deleted when the theme is updated.

that did not change the hyperlink color though? It just changed the font size

Yes, sorry I did size but edited the code.

See code above again
