Hi VQP,
About hover color on titile:
Sorry VQP, there is no customizer setting for changing hover color, the customizer setting given are for link except for post title link. So you need to use custom css for this:
.entry-title a:hover {
color: #cb5544;
}
If you are using plugin, please use this tutorial as a reference : How to use gogle fonts?.
If you got any problems on this please provide us your site Url so we can provide you appropriate solution as soon as possible.
Note: Please use child theme style.css fle to add css, so your changes will not lost on theme update.
Thanks
