Featured post title hover property

Hello

I’m struggling to modify the hover property of the featured post title (currently “Friday’s card”) as I’ve successfully done for other post titles…this in my custom css:

.entry-header .entry-title a {
  color: #3a8f94;
  font-size: 30px;
}

.entry-header .entry-title a:hover {
  color: #153537;
}

Thanks!
