code

You can try:

.crp_related ul li a .crp_title:hover {
    color: #83cdcc !important;
}

You should be able to set the background as well in the same class above

Are you using?

.crp_related ul li a .crp_title:hover {

    color: #83cdcc !important;
    background-color: orange !important;

}

You can change the background colour to whatever you want
