Is that something we want?

In the user session, it affects a lot more bits of UI - not just the 
Shell but also leaf applications. I had assumed we would want to keep 
the default sky-blue in the user session, because that way we get 
consistency between GTK 3 apps (which always have blue accents as far as 
I can see) and GTK 4 apps (which use GNOME's configurable accent colour).
