Darker blue barely distinguishable from black
I'm not sure where exactly to submit this but I will start here.
I have the following darker blue in Help on GNOME OS and Debian testing. People on Fedora 35 don't seem to have it.
While the new blue is great for introducing more contrast in the overview icons it's barely distinguishable from black with text for me. The content feels much less structured to me without this design element.
Another change is that the grey bars behind the header and footer disappeared.
