Dear
@fabiandraxl
There are two different logo's. Every two 'scrolls' or 'slides' the class "white" is added to the site title changing the "background" url.
(standard = black logo)
a.sitetitle {
display: block;
width: 50px;
height: 34px;
background: url(/wp-content/uploads/2019/01/ST_Logo_test-03-03.svg) no-repeat center center / contain;
}
(white 'class added' = white logo)
.sitetitle.white {
background: url(/wp-content/uploads/2019/02/ST_Logo_test-03-03_WHITE.svg) no-repeat center center / contain;
}
Also this link will help with use of the Developer tools where you can inspect a page:

Hope this helps & best wishes π
