The Special Containment Procedures (SCP) Foundation Practice Test

The main idea here is how LRC color codes communicate containment status, especially extreme scenarios. Black is used to signal a breach involving a threat that cannot be terminated—a Non-Terminable Threat that has escaped containment. Since such threats are irredeemably dangerous and not stoppable, the classification must reflect that total, uncontainable escape, which is why Black is the best fit. The other colors describe different, less severe statuses, so they don’t convey the same irreversible breach.
