80B KB12 Circular Cooling Filter
This 55mm Deep Blue KB-12 filter is used to balance daylight film under artificial, tungsten or standard (household) incandescent lighting. The 80B series filters increase color temperature from 3400 to 5500K.

Underexposing with this would also shift the sun's light into the blue-ish night-time hue one expects.

B for Blue, I suppose.
