Hey,

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):

.light h1, .light h2, .light h3, .light h4, .light h5, .light h6, .light p {
    color: #c7d976 !important;
}
.full-width-section > .col.span_12.dark h1, .full-width-content > .col.span_12.dark h1, .full-width-section > .col.span_12.dark h2, .full-width-content > .col.span_12.dark h2, .full-width-section > .col.span_12.dark h3, .full-width-content > .col.span_12.dark h3, .full-width-section > .col.span_12.dark h4, .full-width-content > .col.span_12.dark h4, .full-width-section > .col.span_12.dark h5, .full-width-content > .col.span_12.dark h5, .full-width-section > .col.span_12.dark h6, .full-width-content > .col.span_12.dark h6{
    color: #f00 !important;
}

Thanks
