What is Grayscale?

Grayscale (also called black and white or monochrome) is an image representation where each pixel contains only intensity information rather than color. Instead of three color channels (red, green, blue), grayscale images use a single channel with values typically ranging from 0 (black) to 255 (white), creating 256 shades of gray.onlinetools+1​
