Very interesting and true.

Reminds me when my mom taught me that in oil paintings the “black” colour of a scene should be made by mixing all the colours used - there is information in “black”. Look closely at an oil painting, you’ll see that “black” has hues of red in it.

Also interesting, in the winter an asphalt road is even less black than typical due to the evaporated salt on it. This is a key way to notice if your tires will have grip on it (if a patch looks black, it could be black ice).
