Global Notice should be Red (CSS gets overwritten)

I just asked me why the global announcement (global notice in the admin panel) isn’t red because thats something I would use if there is something really important to say to all my users that should grab a lot of attention. And I looked into the CSS to change it by myself and I saw, that the red background from the global notice is overwritten by the .alert.alert-info. I think that was not the intention here or do I miss something?

(I am not sure about the bug category here on the forum, cause this does not prevent discourse to function, but it seems not typical, like it was intended, so is this category the right place for this?)

It is the correct color as intended you can override it to taste on your site.
