Colour Codes

The Colour Codes are a system used to relay information of emergencies to Blitz Subterranean Research Facility.

## Yellow

Code Yellow calls for visitors and non-essential employees to evacuate to the Topside Meeting Point and stay alert for further instructions. It is called in one of two circumstances:

### High Temperatures

Should the core exceed 4000°C, a Code Yellow will be called. If the employees want to (usually they do), they can activate the Safeguard after a Facility Control Operator turns the correct key. Everything returns to normal if the facility safeguard succeeds, but it will advance to a Code Red if the core exceeds 4500°C or the safeguard isn't deployed.

### Low Temperatures

Should the core drop to 500°C, a Code Yellow will be called. Some employees overload the lasers, others attempt shutdowns. If either succeeds, the facility returns to normal. If the reactor reaches 100°C, it will automatically attempt shutdown. If this fails, the Code Yellow will advance to a Code Red.

## Red

Code Red calls for all visitors and non-essential employees to evacuate to the bunker or any secondary evacuation zone. It is called in one of four circumstances, which are usually irreversible:

### Meltdown

If the reactor exceeds 4500°C or the safeguard fails, a Meltdown will occur. By now, the stabilisation ring will be around 30% integrity. When the stabilisation ring is destroyed, the facility moves to Code Black.

### Freezedown

This occurs after a shutdown failure and the core temperature falls to -150°C or colder. The core loses its colour, and Order 405 causes a power purge, which almost always fails. The core eventually completely freezes over and the rest of the facility goes with it. Strangely, the stabilisation ring doesn't degrade.

The next two have special Code Red screens.

### Warhead Arming

If a person breaches the High Security Area's security measures and begins the warhead arming sequence, a Code Red is called. This is the only Code Red that can be reversed. Anyone with Clearance Level 5 may attempt to disable the warhead after getting through the systems, entering the correct code, turning a key, and pressing a button. If the arming sequence is uninterrupted, the Code Red progresses.

### Warhead Armed

The warhead has never progressed this far, but everyone in the facility thinks the following would happen: If the arming sequence is not disrupted, secondary escape routes become available. The bunker life support systems and facility radiation shield are usually forced offline. Most would use the shuttle system to escape. Eventually, the warhead hits and explodes, taking Topside and a large surrounding area with it.

## Black

A Code Black is called during the Meltdown when the stabilisation ring is destroyed. Special Order 761 orders a full evacuation to the bunker or shuttle. Catherine begins to glitch, and CADET takes over as the main announcer. The systems soon die, and all screens display -SYSTEMS DEAD-. A full facility blackout occurs, the bunker locks, and eventually, the reactor explodes, taking the surrounding glass with it.

## Quarantine

Not a colour code, but if a big enough mistake is made in the Biolabs which could result in serious contamination, a Quarantine is declared (colloquially known as a Code Green). Nobody is permitted to enter or leave the Biolabs except for Biohazard Team Omicron.

## White

A Code White signifies a bomb threat. It is called in the event of a suspicious package being discovered, or an actual bomb threat being made. There have been five instances of this since 1960.

## Purple

A Code Purple signifies a hazardous spill. This code is temporarily shown on certain screens for 35 seconds, as this is not urgent enough to warrant total disruption.

## Orange

A Code Orange signifies a magma warning, which could lead to severe disruption. Elevators are not to be used, and Sub-Level 5 is the evacuation point, it being protected from the magma.

## Amber

A Code Amber signifies an active shooter. Immediate exit of the area is the main priority, however hiding is suggested if leaving is impossible. Whilst Security are usually advised to be the only ones fighting, anyone who can may attempt to subdue or kill the attacker as a last resort.

## Crimson

A Code Crimson signifies a fire. The area affected by the fire is to be evacuated calmly. Everyone is to gather at the Topside Emergency Meeting Point. The elevators are not to be used.

## Silver

A Code Silver signifies a violent altercation. Nobody's entirely certain when an altercation is considered violent enough for a Code Silver, but the code has been called more than once. This message disappears after 35 seconds.

## Pink

A Code Pink is called when a typhoon warning is issued. This code was created in 1979 following Typhoon Tip. The message disappears after 25 seconds, but in the event the typhoon hits, a modified version of Code Pink is called which doesn't disappear until the typhoon has passed.

## Aquamarine

A Code Aquamarine is called when an earthquake is detected. As the systems have become more advanced, foreshocks are now sufficient to trigger this code. A Code Jade sometimes follows. Employees are advised to secure any objects that are liable to fall, and hide under a sturdy object, using their arms to protect their head and neck.

## Jade

A Code Jade is called when a mudslide is detected. Leaving the facility is not allowed, and 5 months of supplies are located in Sub-Level 5 for the needs of every employee.

## Amethyst

A Code Amethyst is called in the event of a heatwave. Employees are advised not to overexert themselves and frequent breaks are permitted (and strongly advised). The message disappears after 30 seconds.

## Blue

A Code Blue is called in the event of a medical emergency. This message disappears after 60 seconds and is only shown on non-essential screens. Medical personnel are the only people who need to pay attention to the message.

## Cyan

A Code Cyan is called when there is a system failure. The message disappears after 50 seconds.
