1) I believe separate styling for sticky navigation is in the plan. As for now you would have to use some CSS to style them. Let me know if you need help on that.
.main-navigation.navigation-clone {
background-color: #ffffff;
}
.main-navigation.navigation-clone .main-nav ul li a {
color: #000000;
}
Couple questions for the mobile navgiation:
– Are you using a mobile header?
– Are you wanting to change just the header color or the entire slideout navigation?
