Hey Again,

Could you provide the page url of the page you are referring to ?.  Also you can change the fonts in the Salient Theme Options Panel- >Typography Section .

Best 

Hey Again,

Add this into the Custom CSS box located in your Salient Options panel (All custom css provided is tested in the Live Browser so it will work as intended . If you cant see any changes make sure there is no red cross in the Custom CSS Box as that syntax error would cause all css below it to not show up on the Frontend):

.page-id-4879 .full-width-section>.col.span_12.dark .swiper-slide[data-color-scheme=light] .content h2 {
    color: #00a2e8 !important;
    font-family: 'Open Sans';
    font-weight: 400;
}
.page-id-4879 .full-width-section>.col.span_12.dark .swiper-slide[data-color-scheme=light] .content p {
    color: #00a2e8 !important;
    font-family: 'Open Sans';
    font-weight: 400;
}

Thanks
