Don't worry, took me over a year to find out that dismissing notifications turns the color of your hubwheel back to gray. Thought for the longest time blue-green was the default. 😓
Holy shit. Now it looks weird and I want it blue again.
TO THE RESCUE
It might as well be the default. I'm always vaguely startled when I see the grey after clearing my notifications.
As a dark style user, I really like the neutral grey. I've found myself following up a bit quicker in order to dismiss what I can. One day I hope for a d20 dark. :o
