Joel Yliluoma's arbitrary-palette positional dithering algorithm This paper introduces a patent-free¹ positional (ordered) dithering algorithm that is applicable for arbitrary palettes. Such dithering algorithm can be used to change truecolor animations into paletted ones, while maximally avoiding unintended jitter arising from dithering. For most of the article, we will use this example truecolor
