That would change the highlight animation for all, if you wanted to do it for a specific category you’d have to use

body.category-XXX-bugs .highlighted {
    animation: cat-XXX-background-fade-highlight 2.5s ease-out;
}

@keyframes cat-XXX-background-fade-highlight {
  0% {
    background-color: gold; //new color for cat XXX!
  }
  100% {
    background-color: transparent;
  }
}
