Black is Black?

Dear Readers:

No, this is not a political question, or a case of racism, it's just one of the usual esoteric bits of nonsense I get tangled up with when I'm trying to find out something.

(FOR EXAMPLE: I don't remember how I got to that point, but one day a few years ago I was doing some research into something or other and I ended up reading a 10 page essay in Scientific American on how sandpaper works! Believe it or not I found the article rather interesting, and also found out that it's a perfect topic to get people to leave you alone at a party or social gathering when you don't really want to talk to anyone.)

So, with that in mind I ran across this little gem that proves we don't know as much about the colour black (Or more accurately, the lack of colour) as we think we do.

Surrey NanoSystems is famous for creating Vantablack, a material so black that it absorbs all but 0.035 percent of visible light. That’s a lot. Things basically disappear when coated with the Vantablack carbon nanotubes. And yet, they’ve somehow made the material even blacker. Yes, the blackest black material has become even blacker.

Surrey NanoSystems writes:
This is a new development of the Vantablack process (just out of the reactor). It’s resulted in a coating so black that our spectrometers can’t measure it! Even running a high power laser pointer across it bearly reflects anything back to the viewer.We have never before made a material so ‘black’ that it can’t be picked up on our spectrometers in the infrared.

BUT! If we did apply the same parameters to a question of "Race" we would come up with just about the same comparison!
