Hello,

Unfortunately, in our theme it’s not possible to have a different logo in the fixed navigation.
You can disable it in Theme Options > General > Fixed navigation > Off.
Please, try to add this code in Custom CSS file:

.fixed-header {
    background-color: black;
}
.fixed-header .ubermenu-main .ubermenu-item-level-0 > .ubermenu-target {
    color: white;
}

How to create custom.css you can watch in this tutorial

    width: 50%;
    height: 50%;
    top: 25%;
