There are two different systems of using colors. The bitmap it is the more primitive of the two since it only admits a maximum variation of 256 colors, each pixel having one byte. On the other hand, images that have true color use three bytes per pixel and this triples the result. of possible variations, exceeding 16 million color options and consequently giving the largest image reality.

The history of the pixel dates back to the early 1930s when the concept began to be used for the movie theater. The term pixel referred to a picture element or "picture element".
