I know that I can change that through the ACP. I do that too, but I can't change it completely.
I want to change the categories text color from white to gray.
Here is a picture for a better understanding

Here my css
body.lights-out .chats-list>li:hover {background: #000;color: rgb(148, 148,148);}
.contentItem.title{
color: rgb(148, 148,148);
}
.categories {
color: rgb(148, 148,148);
}
.stats {
color: rgb(148, 148,148);
