If you are in a room with no light sources, shuttered windows, what colour do you see? I would call that black.
Sure, it's rare to be in such a setting nowadays (at least your cellphone indicating it's charging will be there, or there'd be stars or moon outside), but I think caves are perfectly natural, and you get pure absence of light there. Or 10km below the sea level.
As others have pointed out, you rarely even get pure black, especially with text: on top of reasons others have mentioned, displays use subpixel rendering to make an illusion of higher dpi (similar techniques are employed in the print industry).
- dajomu 6y agoSurely one issue with the example of a lightless room (or cave, or trench) is that there is no contrast and no image, just one default colour. The minute you add a light that gives you any kind of contrast you will in the majority of cases get reflections which will make most of the dark areas not completely black.
