Grayscale

An achromatic scale ranging from black through a series of successively lighter grays to white. Such a series may be made up of steps, which appear to be equally distant from one another. If the Analog/ Digital converter is 8 bit, then the monitor can display at most 28 = 256 levels. For a color monitor, R.G.B. each color hads 256 levels. Thus, total color can display is 256x256x256= 16.7 million.
