Question

How do human perceive the black color​

Answer 1

Answer: Photoreceptor cells

Explanation:

The human eye and brain together translate light into color. Light receptors within the eye transmit messages to the brain, which produces the familiar sensations of color. ... Rather, the surface of an object reflects some colors and absorbs all the others. We perceive only the reflected colors thus, we have two types of photoreceptor cells, known as rods and cones. Cone cells deal in colour, while rod cells allow us to see in grayscale in low-light conditions, for example at night.

Answer 2

Answer: The color black is a not a reflection of colors, but an absorption, meaning that all the colors of the spectrum are absorbed by the object.

Explanation: "We see the color of an object because that object reflects “a color” to the eye. ... Black is not a color; a black object absorbs all the colors of the visible spectrum and reflects none of them to the eyes. The grey area about black: A black object may look black, but, technically, it may still be reflecting some light."
