Removing color

Hi,

Im having difficulties to remove color style in my sidebar, its seems inherited with something I Dont know, so i have to use dirty hack in my sidebar to like this:

.Affiliate a:link,
.Affiliate a:visited,
.Affiliate a:hover,
.Affiliate a:active {
color: #719EF1;
border: 2px #719EF1 solid;
}

but in IE, I still see the blue box, its annoying…

Is there anybody can help ?
