Definitions
Grayscale
In digital photography, computer-generated imagery, and colourimetry, a greyscale image is one in which the value of each pixel is a single sample representing only an amount of light; that is, it carries only intensity information. Greyscale images, a kind of black-and-white or grey monochrome, are composed exclusively of shades of grey.
Color
Color (American English), or colour (Commonwealth English), is the characteristic of visual perception described through color categories, with names such as red, orange, yellow, green, blue, or purple. This perception of color derives from the stimulation of photoreceptor cells (in particular cone cells in the human eye and other vertebrate eyes) by electromagnetic radiation (in the visible spectrum in the case of humans).
