This has nothing to do with a single image or so, take a look at other screnshots, e.g., https://openqa.opensuse.org/tests/4305473#step/partitioning_filesystem/14 or even https://openqa.opensuse.org/tests/4305473#step/welcome/3 I don't know what has changed, but more of the colors seem to be different and we haven't changed them.
