Coloring a NavBar Link

On my NavBar I want to color in the link that says "IRC Connect". I had this working in the past but when I changed my forum to phpBB2 it stopped working.

Previously I used this code given to me by rideem3 to make it change color:

Code:

.navlinks a[href="URLHERE"] {
color: COLORHERE !important;
}

Now it is not working

I would like some help on how to restore the color I previously had.

Thanks in advance for all help and replies.

Try this code in the css.

Code:

a.mainmenu[href="URLHERE"]{
  color: #ffffff !important;
}
