A few more accent color things landed, e.g. settings illustrations can now follow it, calculator has dropped orange, new dialogs disambiguate suggested/destructive styles, while papers and sysprof properly redraw when accent changes now (and it's all in gnome os, incl. shell finally). So yeah, it's all in a fairly good shape now ^^ (other than blue folders) (📎4)
I can’t wait until we have themed icons. It is just a matter of time.
A move to SVG generated icons should hopefully fix that. Not sure what stage they are at with that however.
