Is black a color?
There is much debate about whether black is, in fact, a color. It depends primarily on who you ask, though. In computer displays, black is considered a color. This is because in computer code, the color black is represented by the value 0,0,0 which means 0 red, 0 green and 0 blue, and this combination uniquely identifies the color black. In printing, black is also typically considered a color, for example, inkjets usually consist of four colors, Cyan, Magenta, Yellow and Black. These four colors are mixed together to print all other colors. Interestingly, in physics, however, black is not a color because there is no value in the spectrum of light that corresponds to the color black, rather black is made up of the absence of light.
