Trying to change the a:link and a:active colours in JQuery UI tabs

Trying to change the a:link and a:active colours in JQuery UI tabs

Hello I am doing a website for the company I work for and have chosen to use JQuery UI Tabs which work great! Except I cannot work out how to change the a:link, a:active colours in the tabs. I have changed the colours for the rest of the site (using CSS) but the link text in the tabs stays untouched and still show as blue in the browser!? (see screenshot below:)



I am assuming I should be looking at the "jquery.ui.theme.css" but no-where is the #blue colour - so I cant see what I should be changing!

Does anyone know how to do this / what I should be changing?

thanks

Sara.
