Useless Scratch facts # 5:

An early version for a dark mode was implemented in the High-Contrast update, however it goes unused.

TurboWarp implemented it as the "Dark (Beta)" option. It's marked as beta because it's subject to upstream changes.

A minor update has been released for Unsandboxed. Full changelog is in the article.

The code and assets for it still exist and are even implemented in some mods.
