Rollover color in nav menu

Hello Brilliant WordPress People,

I’m trying to change the rollover color in my nav menu, but for the life of me, i can’t figure it out.
I was able to change the rollover for the line below, but not for the link itself.
Can someone look at the css, and tell me what i’m doing wrong? Thanks for any help. ??

}

.black-content .icon-bar {

position: absolute;
bottom: 0;
left: 0;
width: 100%;
