“dark light. [Not actually an oxymoron. It's the color past ultra-violet. The technical term for it is infrablack. It can be seen quite easily under experimental conditions. To perform the experiment simply select a healthy brick wall with a good run-up, and, lowering your head, charge. The color that flashes in bursts behind your eyes, behind the pain, just before you die, is infra-black.]”
