“Color is a sensation,” he was saying. “It has no objective reality. Without light, we can see neither colors nor objects themselves. All objects are black in the dark, and in the dark it is impossible to see them. If no light strikes upon them, then no light is flung back from them to the eye, and so we have no vision-evidence of their being.”

“But we see black objects in daylight,” I objected.

“Very true,” he went on warmly. “And that is because they are not perfectly black. Were they perfectly black, absolutely black, as it were, we could not see them—ay, not in the blaze of a thousand suns could we see them! And so I say, with the right pigments, properly compounded, an absolutely black paint could be produced which would render invisible whatever it was applied to.”

...I visited Lloyd’s laboratory a number of times after that, and found him always deep in his search after the absolute black. His experiments covered all sorts of pigments, such as lamp-blacks, tars, carbonized vegetable matters, soots of oils and fats, and the various carbonized animal substances.
