Is Black A Color?

Solution by @Krishna Kanth Dasari . Black is the absence of all visible radiation! When any electromagnetic radiation of visible wavelength reaches our eye and our brain makes the illusion of color, the color for each wavelength is unique. But black color is not associated to any electromagnetic radiation rather the absence of all the visible radiation (could be absence of all type of radiations also). It's a blank in the colorful world, our brain fills that blank with a perception of black color we see.

Black is the perception of our brain when no wavelength reaches the retina. For example, in the atmosphere of moon, the lack of a wavelength , it apears black. So, strictly speaking, black is not a colour. Similarly, white too is not a colour because it is the sensation in the brain when all the wavelength reaches the retina simultaneously, thus the final sensation in our brain after travelling through the optic nerve gets so messed uo that we perceive white. So, white too is not a colour.
