You can try this with jQuery SetInterval
For this you don't need to include animation css at the beginning
CSS:
.header-text {
display: flex;
flex-direction: column;
float: right;
text-align: right;
align-content: center;
justify-content: center;
}
.head-text {
font-family: 'Lato', ;
color: white;
float: right;
font-size: 4rem;
}
.head-desc {
font-family: 'Lato', ;
color: white;
float: right;
font-size: 3rem;
margin-top: 0;
}
#keyframes color-swap {
from {color: white;}
to {color: black}
jquery
<script

$(document).ready(function(){
setInterval(function(){
$(".head-text .head-desc").css({
"animation-name":"color-swap",

}, 3000);
}
