Explanation:
Detailed explanation-1: -The number of bits determines the range of colours. This is known as an image’s colour depth . For example, using a colour depth of two, ie two bits per pixel, would allow four possible colours, such as: 00-black.
Detailed explanation-2: -The higher the color depth, the better your images will generally look on the screen. Images viewed at the 16-colors setting will usually look less refined than the same images viewed at the 256-colors setting because there are not as many colors to display tones and variations.
