Hi all. I have a couple questions regarding the “color” black. First question, regarding reflected light: Would a perfectly black object with no reflectiveness to its surface absorb 100% of the light that hits it? If so, would it activate no rods/cones on the observer’s retina whatsoever, and essentially be a blank spot in their vision that appears pure black? Is such a thing even possible (outside of a black hole)? Second question, regarding emitted light: I know that some TVs and other types of screens are capable of producing darker blacks than others. How can something that emits light emit black at all when it is actually the absence of light? Wouldn’t it just not activate its LEDs (if it’s an LED display) for the areas of the screen it wants to be darkest? Thanks!
