Hi,
Did you mean the title and the bottom bar color of the testimonials? Do you want them same colored? Then you may use the following code in your custom CSS:
.edulif-instructor-home-testimonial-wrapper .sppb-carousel-extended-list .sppb-carousel-extended-outer-stage .sppb-carousel-extended-item:after, .edulif-university-home-testimonial-wrapper .sppb-carousel-extended-list .sppb-carousel-extended-outer-stage .sppb-carousel-extended-item:after {
background-color: pink !important;
}
.edulif-instructor-home-testimonial-wrapper .sppb-carousel-extended-list .sppb-carousel-extended-outer-stage .sppb-carousel-extended-item .sppb-testimonial-carousel-name-designation .sppb-testimonial-carousel-name, .edulif-university-home-testimonial-wrapper .sppb-carousel-extended-list .sppb-carousel-extended-outer-stage .sppb-carousel-extended-item .sppb-testimonial-carousel-name-designation .sppb-testimonial-carousel-name {
color: red !important;
}
Note: Path towards custom CSS(Joomla 3): Extensions>Templates>Styles> Click on your current default template name then choose Template Options. Then find custom CSS within the custom code.
Best Regards
