That requires color quantization and it requires the index assignment to be incorporated into the error diffusion process. I don't have an example for that.

Half-Toning: Ordered Dithering - Medium

WebJan 7, 2011 · The quick-and-dirty halftoning I implemented above is a form of ordered dithering. The randomness of the noise mask is replaced by a fixed, repeated pattern. However, clustering the “on” pixels in this way creates strong artefacts (the dots!) that are not necessary for electronic displays.
