Dithering allows an image to be represented by a smaller number of colors. Each pixel is rounded to the closest color from the given palette, and the error is rounded to the surrounding pixels. Dither Studies exposes this process by dithering solid colors or simple gradients using a palette of complementary colors. Although the dithering algorithms are rooted in a simple logical process, the resulting patterns appear complex and irrational.
