Item #: SCP-712

Object Class: Safe

Special Containment Procedures: SCP-712 is stored fully assembled in a secure storage room at Research Site-14. The room's air is to be HEPA filtered and anyone entering must wear a clean room suit to minimize introduction of dust that could interfere with the optics of SCP-712. Anyone making adjustments to the components of SCP-712 must wear non-powdered nitrile gloves; latex gloves are not permitted as Dr. ███████ is severely allergic. The vibration-absorbing base of SCP-712 is attached securely to a 1.5 meter high table that is securely bolted to the floor of the room. The layout of this secure storage room is an "L" shape with the apparatus aimed at the far wall perpendicular to the door. No video recording devices are permitted in the room and all cameras viewing the entrance are to be fitted with one Wratten #90 filter and one linear polarizing filter with the axis of polarization oriented horizontally.

The emitting lens of SCP-712 is aimed at the rear wall and optical targets should be kept behind the apparatus except during testing. A SWNT forest panel is in place in front of the emitting lens of SCP-712 as a component of the fail-secure system. The rear wall of the room is tiled with SWNT Forest light absorbing panels. 10 (ten) standard 300 watt metal halide floodlights are aimed at the target wall and are to be turned on no less than one hour before SCP-712 is connected to a power supply to ensure that the color temperature has stabilized at 5000K. These floodlights are shuttered as a component of the fail-secure system.

A fail secure system is installed in the room. During operation, the floodlights will be shuttered and the panel in front of emitting the lens will retract. The researcher conducting an experiment must maintain constant pressure on a thumbswtich, and a bite plate will detect jaw clenching that may indicate a seizure. If pressure on the thumb switch is released, pressure on the bite plate exceeds normal limits, or power to the system is lost, the shutters covering the floodlights will drop away and the light absorbing panel will drop into place in front of SCP-712's emitting lens. An emergency power shutoff switch that will disconnect power to SCP-712 is mounted in the observation area.

All personnel and test subjects who are present when SCP-712 is powered are to be administered vision tests to measure distance vision, near vision, and color perception before entering the room and immediately after leaving. Unless authorized by Dr. ███████ in writing and approved by a Level 4 staff member, no individual who exhibits any degree of colorblindness is permitted to enter the room. Individuals who exhibit diminished visual ability after an experiment will be held for observation for 24 hours and tested before being released. Any individual who continues to exhibit diminished visual ability after the 24 hour observation period will be prohibited from working with SCP-712 and reassigned to a non-research position for an additional 30 days. Individuals exhibiting diminished visual ability after 30 days will be permanently reassigned. No individual who exhibits any diminished visual ability after 24 hours may be assigned to experiment further on SCP-712.

Research on SCP-712 is coordinated by Dr. ███████.

Description: SCP-712 is an apparatus that emits electromagnetic radiation at one of two frequencies defined by the formulae [REDACTED] and [REDACTED]. The wavelength and frequency of both emitted frequencies are expressed as complex numbers and therefore do not fall within the conventional electromagnetic spectrum. When the radiation emitted by SCP-712 illuminates most objects capable of reflecting visible light, the target object will phosphoresce and emit one of two "Impossible Colors." [See Addendum A.]

The radiation emitted by SCP-712 is has been designated SCP-712-1, and the colors produced by target materials have been designated SCP-712-a and SCP-712-b.

While prior published research into impossible colors had achieved limited success by projecting one of two component colors into each eye of participants, SCP-712-a and SCP-712-b are each discrete colors. While the colors of SCP-712 can be perceived by human subjects, their wavelengths are expressed as complex numbers rather than wavelengths found in the visible spectrum. Specific information can be found in Dr. ███████'s research notes.

Subjects who view these colors report feelings of unease or awe, with neither corresponding to particular post-exposure effects. Approximately 26% of subjects experience no effects after viewing SCP-712a or SCP-712-b. Approximately 74% of subjects experience diminished visual ability after viewing SCP-712a and SCP-712-b; approximately 95% of subjects who initially display diminished visual ability recover within 24 hours. Approximately 1% of subjects who experienced diminished visual ability after 24 hours did not recover.

SCP-712 is a light-emitting apparatus that was removed from the laboratory of Dr. ██████ ███████████ at █████████ University.

SCP-712 is mounted on a vibration damping base. Components are labeled with stamped metal plates, and a plate at the front of the apparatus is stamped "f=9907mm." A cord with four wires protrudes from the power supply, which is labeled in permanent marker "220v." The apparatus consists of a LASER emitter, a series of fiber optic tubes, and modulating elements consisting of [DATA EXPUNGED]. The emitting lens is an optically transparent lens composed of an unknown material with a refractive index of .0003

Each of SCP-712's variable elements is mounted on a keyed base that fits into one of two slots labeled "A" and "B." An interlock system prevents the power supply from providing power to SCP-712 unless all elements and switches are set to either "A" or "B."

Do not make any adjustments to SCP-712-1 unless you have verified that power is disconnected. If you feel that basic safety rules do not apply to you, I will be more than happy to reassign you to a position in which your risk of injury will be limited to papercuts and writer's cramp. - Dr. ███████

Common Effects of SCP-712:
The following effects have been observed in subjects exposed to SCP-712:

— Perceived desaturation when viewing colors in the visible spectrum. After viewing SCP-712-1a, subjects perceive desaturation of yellow and blue colors; after viewing SCP-712-1b, subjects perceive desaturation of red and green colors. This is the most commonly reported effect.
— Viewing SCP-712-a and SCP-712-b has triggered severe migraine headaches with visual aura in subjects predisposed to migraines on several occasions.
— Diminished ability of the subject's eyes to focus visible wavelengths of light while retaining the ability to focus SCP-712 wavelengths.
— Temporary complete blindness to the visible spectrum has been observed in two subjects. Both subjects recovered within the 30 day observation period.
— Grand Mal seizures. Before the recovery of SCP-712, Dr. ██████ ███████████ appeared to have suffered a Grand Mal seizure. During initial experimentation, two subjects diagnosed with epiliepsy suffered seizures.
