Changing color of arrow

I need to change the color of the active slide item from orange to another color. I've been able to change the arrow images (orange_roll.png, orange_arrow.png), but can't find the code for the center part.

That is in modules/mod_hot_designation/tmpl/hot_designation.css

.hjt-gallery-list-item-selected td.hjt-gallery-list-item-thumb, .hjt-gallery-list-item-selected td.hjt-gallery-list-item-content {
background: #FE6F00;
color: white;
}
