Out of the box theme doesn’t have the option to adjust the animated GIF color. Please add the below CSS to resolve your site issue.
@-webkit-keyframes preloader {
0% {
height: 5px;
-webkit-transform: translateY(0);
background: #c4c700;
}
25% {
height: 30px;
-webkit-transform: translateY(15px);
background: #c4c700;
}
50% {
height: 5px;
-webkit-transform: translateY(0);
background: #c4c700;
}
100% {
height: 5px;
-webkit-transform: translateY(0);
background: #c4c700;
}
}
@keyframes preloader {

}
25% {

You can change the color by tweaking background values if necessary.
