Single Course Header Font

I am attempting to change the following font colors in the single course view: breadcrumbs item-admin reviews students screenshot: https://prnt.sc/ify1fz I currently have a light background and the font is white which makes this information barely readable. I've attempted to change these myself, but nothing I enter is working: ex: .single-course.c2 .course_header #item-admins h3, .single-course.c3 .course_header #item-admins h3 { font-color: #444 !important; } #item-header.light { font-color: #444 !important; } .breadcrumbs { display: inline-block; padding: 0; margin: 0; list-style: none!important; font-color: #444; } I've checked the typography in appearance > customize > typography and nothing there is set to white font. I checked all the custom CSS I've entered and nothing there is set to white font. If you can tell me where this can be changed I would greatly appreciate it.
