Dithering is the technique of using lots of different coloured pixels to make it appear as if you have more colours available then you really have. In the simplest case, imagine a computer screen where every pixel can only be black or white. How can you simulate shades of grey? The answer is to put the right number of black or white pixels close together, so that it gives the vague impression of grey.
