In [[computing]], a '''grayscale''' or '''greyscale''' [[digital image]] is an image in which the value of each [[pixel]] is a single [[sample (signal)|sample]]. Displayed images of this sort are typically composed of shades of [[gray]], varying from black at the weakest intensity to white at the strongest, though in principle the samples could be displayed as shades of any color, or even coded with various colors for different intensities. Grayscale images are distinct from [[black-and-white]] images, which in the context of computer imaging are images with only two [[color]]s, [[black]] and [[white]]; grayscale images have many shades of gray in between. In most contexts other than digital imaging, however, the term «black and white» is used in place of «grayscale»; for example, photography in shades of gray is typically called «black-and-white photography». The term '''[[monochromatic]]''' in some digital imaging contexts is synonymous with grayscale, and in some contexts synonymous with black-and-white.
