Hello,
Please add the below given CSS to change the background color of the icon container option and to change the hover color of the site title on scroll to
Dashboard -> Appearance -> Customize -> Additional CSS
.corporate_key_widget_services .service-block-inner > a {
background: #90320d;
}
//site title color on fixed header
.home.header-overlap-enabled #masthead.fixed .site-branding a:hover, .home.header-overlap-enabled #masthead .site-branding a:hover {
color: #171615;
}
Now for the hover color of the services box you can change it form
Dashboard -> Appearance -> Customize -> Home Page Widgets Color Options and change the Link Hover Color option to your preferred color.
Hope it helps.
Regards.
