Home page circle icon widget font color

Hi,
I have tried to change the font color on Circle Icon widget with no success.

I tried on each of the widget individually, at the attribute, without any success
Classname: mytest
.mytest{
color: #FFF !important;
}

I tried it on the css editor, without success
.home .widget_circleicon-widget .circle-icon-box {
color: #FFF !important;
}

But, if I put it as without the “.home”, it works,
.widget_circleicon-widget .circle-icon-box {
color: #FFF !important;
}

How do I make it only applicable to the home page only?

Thanks.
