is white, which has the maximum presence of colour of value 1 for the pixel. In grayscale images, the shades range
starts with 0 and ends with 255, i.e., it starts with pure black and ends with pure white.
A grayscale has each pixel of size 1 byte having a single plane of 2-dimensional array of pixels.
RGB Image
All coloured images around us are made up of three colours with varying intensity – Red,
Green, and Blue. Every coloured image, when split, is stored in the form of three different
channels, i.e., R Channel, G Channel, and B Channel. Each channel has a pixel value varying
from 0 to 255. For example, RGB value of Aqua colour is (0, 100, 100).
