When a lurking mathematician, Brent Werness, invents a sweet new type of detail preserving dithering for Obra Dinn as a devlog comment. https://forums.tigsourc

  Another interesting way of dithering would be http://johanneskopf.de/publications/blue_noise/ http://johanneskopf.de/publications/blue_noise/ but that might take away from the sought aesthetics.

    The game's author Lucas Pope compares the new dithering with blue noise here : https://forums.tigsource.com/index.php?topic=40832.msg1217196#msg1217196 https://forums.tigsource.com/index.php?topic=40832.msg121719... Visually Werness algorithm is the best, and Pope concludes: "What Werness built is a hybrid between noise thresholding and progressive error diffusion... he's turned the algorithm inside out - instead of spreading one pixel's error to its neighbors, each pixel sucks up the error of its neighbors... this affects a diffusion of the errors.
