Detailed explanation-1: -whole bytes (24 bits) are used to represent the colour of each pixel. This is split up into one byte for each of the primary colours of light, red, green and blue.
Detailed explanation-2: -Each pixel is represented by a 4-bit number, so there are 2^4 = 16 colors in the color table. Each color in the table is represented by a 24-bit number: 8 bits for red, 8 bits for green, and 8 bits for blue.
Detailed explanation-3: -Pixels store color information in a specific number of computer bits, ranging from one bit to 48 bits. A pixel with one bit can display only one of two colors – either black or white. As bit depth increases, so does the number of colors available to display.
Detailed explanation-4: -RGB colors are most often represented using 8 bits per color component, a total of 24 bits to represent a color. This representation is sometimes called “24-bit color.” An 8-bit number can represent 28, or 256, different values, which we can take to be the positive integers from 0 to 255.
