Please use below given CSS to change the white text in black color in responsive view.

Hello @jmarkantonakis,

If we change the background of the site title text then the site title itself will be hidden.

But if you still want the header background to be black then use below given CSS.

@media only screen and (max-width: 767px){
.site-header {
    background-color: #000; 
}
}

Also, the theme has provided the option to change the color of the header section so please go to Admin Panel > Appearance > Customize > Color Options > Header Color Options and change the color as per your requirement.

HOpe this helps.

Best Regards!!
