Grayscale is a term used to describe an image or display that is made up of shades of gray, rather than full color. In a grayscale image, each pixel is represented by a single value that corresponds to the brightness or intensity of that pixel, ranging from 0 (black) to 255 (white), with various shades of gray in between. #grayscale
