Content notes

This is psychological horror. It works by making you read documents written by people who knew something was wrong and filled in a form instead of stopping it. It does not work by making you jump.

The short version

• No jump scares. Nothing lunges at the screen and nothing spikes the volume.
• No gore. There is no on-screen violence and no body horror imagery.
• No chase. Nothing pursues you. You cannot die and you cannot be caught.
• No timers. You can stop reading and come back.
• Recommended 16+ for themes rather than for imagery.

Themes present, without spoilers

• Sleep deprivation used as an experimental method on consenting-on-paper adults.
• Institutional negligence: procedures followed correctly while producing a bad outcome.
• Medical and psychiatric research conducted without meaningful oversight.
• A staff member raising a formal objection and being administratively overruled.
• Documents that record distress in flat clinical language.
• Isolation, disorientation and unreliable memory.
• An unexplained disappearance, referred to in records rather than shown.

Not present at all

• Sexual content or sexual violence of any kind.
• Harm to children or animals.
• Suicide, self-harm, or method depiction.
• Racial, homophobic or transphobic slurs.
• Real-world conspiracy content. The word in the title is a colour designation in this story — a lighting gel — and the game does not engage with the theories attached to it elsewhere.
• Depiction of real people, real institutions, or real events.

Sensory notes

• Lighting flicker in two rooms. Removable with reduced motion; nothing flashes more than three times per second in any mode.
• Low-frequency room tone throughout. Adjustable and mutable, and never carries information.
• Tape hiss and dropout on recordings. Every recording also has a full written transcript.
• Film grain and scanlines on surveillance footage. Removable with reduced motion.

All of these are in settings and in the in-game pause menu.

Spoiler-level detail

If you would rather know exactly what is in Chapter One before you start, the list below names specific moments. It gives away plot.

Show specific content for Chapter One

• An audio log recorded by a technician who has been awake for thirty-one hours and knows it. Her speech deteriorates over the recording. She is not harmed on tape.
• A written objection from a staff physician listing six concerns, the sixth of which is redacted until you solve a puzzle. When recovered, it describes a subject kept awake past the protocol limit at a supervisor's direction.
• An observation chart showing a subject's hourly state over fourteen hours, ending with entries a reader will find distressing in their blankness.
• A surveillance clip in which a member of staff enters an observation room, stands still for ninety seconds, and leaves. Nothing happens to them.
• A choice about whether to include a colleague's name in your assessment, knowing what it will cost her.
• One ending in which the facility's record is corrected and one in which it is not, and you choose which.

If it stops being enjoyable

Stop. Progress is saved continuously, so leaving mid-room costs you nothing. If a specific element is the problem and it is not covered by a setting, tell us through the contact form — we would rather add a toggle than lose a player.
