* Dithering

Dithering is the act of reducing an image's palette by different means. It is a
common way to reduce file sizes.

** Floyd-Steinberg

One of the most well-known dithering algorithms is the Floyd-Steinberg
algorithm. It is based on spreading out rounding errors of individual pixels
onto its surrounding pixels.
