Ever have problems setting the color for the header search icons?
Normally, search box setting are in Customizer > Header > Menu > Search Icon. However, the icon colors need a little bit of css. Try the following and change the colors to your preference.
#site-header i.icon-magnifier {
color: #fff;
}
#site-header i.icon-magnifier:hover {
color: #ffff19;
