Fortunately, there’s now a mod that lets us import that look to SkyUI.
It hadn’t occurred to me that its monochrome minimalism might be kinda ugly too, but I’m reconsidering that in comparison with the classic parchment look of predecessor Oblivion.
In fact, it’s so crap that one of the game’s most downloaded mods is SkyUI, which neatly streamlines everything for PC players. Vanilla Skyrim’s UI is, famously, pretty crap.
