Item #: SCP-613
Object Class: Euclid
Special Containment Procedures: Any subject contaminated by SCP-613 shall be confined in a normal detention cell, furnished as requested provided items do not violate standard security or containment procedures. Personnel entering this cell must wear full-body clothing to prevent accidental direct contact. The detention cell's walls should be built of concrete no less than 1.5 meters thick. All objects that have been affected by SCP-613 are to be incinerated or otherwise destroyed once they are no longer useful or after the subject has recovered. The cell should be isolated from the outside world with biosafety level 4 material and measures to prevent spread via microorganisms. Only desaturated material, and no original photographs, electronic files, film etc. may come within SCP-613's containment cell. Every six weeks, a new carrier shall be designated for infection. Carriers, if D-class, are terminated per normal procedure after they have healed. It is recommended that no fewer than two separate sites should maintain their own series of carriers, to reduce the risk of containment breach due to premature carrier death.
Description: SCP-613 is an infectious agent transmitted by physical contact. Contaminated organisms gradually lose all color saturation, becoming living "black and white" characters over the course of a few days, at which point they become contagious. Once the brain and eyes are affected, carriers also lose the ability to perceive, or even remember, what colors are. The disease is transmitted by touch to any organism, with the color loss spreading from the point of contact. This spread varies depending on material density. All known living organisms may be affected and transmit the disease, including microorganisms, making containment difficult.
Infected organisms gradually heal over time, reflected by the return of their natural pigmentation. Contagiousness is lost once color saturation has returned. The subject's biological complexity appears to influence the speed of recovery: microorganisms heal in a day or two, insects and small invertebrates in a week at most, plants in roughly four weeks, and humans in roughly eight weeks. The only lasting effect is a complete and retroactive colorblindness. There have been no known cases of re-infection once the organism has healed. If the last carrier heals or dies, the disease is, upon loss of contagiousness, instantly transmitted via an unknown process to the most recent organism which touched that carrier without becoming infected. Because of the difficulty in tracking the newly infected carrier, it is crucial that a new carrier be infected before the current one stops being contagious.
Touch from a contagious subject will affect inanimate materials. Spread in liquids is slower than in solids, while gases are unaffected. Metals are the most rapidly affected materials. Spread in inanimate objects occurs to a maximum distance of approximately 1 meter, and only during active contact. However, the effects remain once contact has stopped. Objects affected also cause any files or signals carried, executed, or stored on them to permanently stop carrying any saturation information. It is not possible to paint, dye or draw over the objects with colored substances, though wallpapers and similar cover can be used, and this does not seem to affect colored light projected on them either.
Addendum 01: Please respect SCP-613 carriers and stop referring to them as "silent movie escapees". - Dr. Fries
