In reference to darkroom safelights, to what do the initials 'OC' refer?

It's an old Kodak-Wratten designation for a yellowy-orange safelight filter. In other words a "standard" orange B&W printing safelight.

Just a guess. Orthochromatic, perhaps? Signifyig its safe for using with orthochromatic materials..... DJ
