When I read this article I immediately thought of the wisecrack that when a color darker than black is invented, New Yorkers will wear that:
A British company has produced a “strange, alien” material so black that it absorbs all but 0.035 per cent of visual light, setting a new world record. To stare at the “super black” coating made of carbon nanotubes – each 10,000 times thinner than a human hair – is an odd experience. It is so dark that the human eye cannot understand what it is seeing. Shapes and contours are lost, leaving nothing but an apparent abyss.
Sadly, the cost of a fabric made along these lines would probably be high enough that its use in apparel is unlikely for some time. Not that that will stop some people.
