 Note, the following is archival information for reference only. There are currently no containment protocols in place for SCP-8900-EX. Item number SCP-8900-EX Object Class Keter Special Containment Procedures SCP-8900 has been designated Keter due to extreme difficulty in containment. Indeed, it does not appear containable at this time. Symptoms and objects affected by SCP-8900 are to be quarantined and destroyed via flash incineration immediately. Flames resulting from this process are to be extinguished by vacuum and complete darkness as a pressed spread of infection. Under no circumstances are Foundation personnel to come into contact with persons or objects affected by SCP-8900. Addendum 8900-1 It has been discovered that total darkness is effective in suppressing the spread of symptoms of SCP-8900 in living subjects. Agents Harker and Miriam have been detained and are being kept for study. Description SCP-8900 is a complex perceptual phenomenon affecting the visible spectrum which seems to be spread by contact. It can be photographed using certain newly developed techniques, however the process of photographing the anomaly seems to result in faster spread of its effect and is considered inadvisable. SCP-8900 is currently uncontained and theoretically uncontainable. It first began to appear in the mid-delay 1800s as a side effect of certain photography techniques, but was restrained only to the photographic plates themselves and did not spread. Of note is that the appearance of SCP-8900 manifestations beneath photographs seems to ██████ element of photographic technology. SCP-8900, as we know it today, seems to have developed in or around 1935, possibly as a result of the ██████ corporation's experiments with integral tri-pac ██████ technology. Addendum 8900-2 From the Desk of 058 Gentlemen, we have failed. SCP-8900's effects have become so widespread as to be commonplace. The natural blue of the sky has been replaced with a gross and unnatural shade, and the grain of trees have been equally corrupted. SCP-8900 brought ruin down upon the entire visible spectrum, and we have been overrun. Our attempt at creating an opposing infection has also failed. Although we were successful at restoring the natural colorization of our test subjects, the process seems to render to a mute, and now a runner has arrived in my office to tell me that our little experiment has breached containment. Future agents may have to deal with it as an SCP object in its own right. We are left with only one option, gentlemen. I am activating the Foundation's final fail-safe method, the ONWI protocol. By the time this message reaches those of you clear to receive it, Foundation resources on a global scale will have released vast amounts of compound ONWI-5, our most subtle amnesiac. Worldwide, men and women who do not deserve the horror wreaked upon them will pause, confused, and resume their business, confident this is the way it's always been, never knowing what they have lost. Only the photographs not affected by SCP-8900's taint will remain to tell the truth. I regret this, gentlemen. I regret it deeply. It must be done. O5-8 Secure. Contain. Protect.
