A '''pixel''' (which is short for "picture element") is the smallest part of a [[digital]] image. The size of the pixel depends on the [[resolution]] of the image display, in other words, it is as large or as small as the user chooses to display it. The color of a pixel is some combination of [[red]], [[green]] and [[blue]] (also known as RGB). Pixels are most often squares in computer displays, but they do not necessarily have to be squares.
