Dithering was originally invented to make limited color displays appear to show more colors than they physically could. The human eye blends tiny dots together, creating the illusion of depth and shading.
Image dithering dates back to early printing and computer graphics. Before modern high-color monitors existed, computers and printers could only display a small number of colors. Algorithms such as Floyd-Steinberg were developed in the 1970s to simulate gradients and complex imagery using only black and white or a very small palette. These techniques powered early Macintosh graphics, classic video games and digital art, and they remain popular today for their unique aesthetic style.
