This is the dark colour scheme used in Feren OS releases between December 2019 Snapshot and July 2020 Snapshot. It's based on the original Feren OS theme design used at the time, before being replaced with an entirely new theme, taking heavy emphasis on user and developer feedback, after July 2020 Snapshot.

Variants:
Original: The unfixed version with rather bad contrast that was present in Feren OS during this theme's lifetime
Fixed/Nameless: The same colour scheme but with its view background changed to match the theme used in Feren OS during this theme's lifetime
