You're in a security room in The Vellums Station. The hue of everything slowly cycles through the spectrum and the room's decor has a ruined, rustic style.
You're in Tubes of the Gateways. Collections of large, luminous maroon crystals are growing everywhere and a heavy, old door is set into a nearby wall.
You're in Dungeons of Shakedown. Floating groups of small, magenta lights dance about and a wide shaft of blurple coloured light pokes through a hole above.
