Hi,
This feature is not available in the free version you have to upgrade to the premium version of the FolioPress theme to easily change the default theme color to your own.
Anyways just go to Appearance > Customize > Additional CSS
and paste the below custom CSS code to change the header link color as well as borders:
.site-title a:hover,
.site-title a:focus,
.site-title a:active,
.main-navigation a:hover,
.main-navigation ul li.current-menu-item a,
.main-navigation ul li.current_page_ancestor a,
.main-navigation ul li.current-menu-ancestor a,
.main-navigation ul li.current_page_item a,
.main-navigation ul li:hover > a,
.main-navigation ul li ul li a:hover,
.main-navigation ul li ul li:hover > a,
.main-navigation ul li.current-menu-item ul li a:hover,
.navbar span.search-toggle:hover {
color: #50C3DC;
}
.post-grid .entry-title:after,
.widget-title:after,
.entry-title:after,
.page-title:after,
.post-grid .sticky .sticky-post {
background-color: #50C3DC;
}
Note: Change the above HEX color code #50C3DC
to your own HEX color code to change the color.
Thank you for using our theme.
