Slider navigation color

Hi,

I am trying to change the color of the slider navigation (the dots) from white to green. I was able to change the hover color to green by changing the background like this:

.flex-control-nav li a:hover {
background: rgba(95,175,0,.8);
}

But I can’t change the color when it highlights the location of the link dot.

I have changed

.flex-control-nav {
color: #5FAF00;
}

.flex-control-nav li {
color: #5FAF00;
}

.flex-control-nav li a {
color: #5FAF00;
}

But they don’t do anything… 🙁
