A notable resource on the topic of ordered dithering using arbitrary palettes is Joel Yliluoma’s Arbitrary-Palette Positional Dithering Algorithm. One key difference of Yliluoma’s approach is in the use of error metrics beyond the minimisation of . Yliluoma notes that the perceptual or psychovisual quality of the dither must be taken into account in addition to its mathematical accuracy. This is determined by use of some cost function which considers the relationship between a set of candidate colours. The number of candidates, the particular cost function, and the thoroughness of the selection process itself give rise to a number of possible implementations, each offering varying degrees of quality and time complexity.
These optimizations are difficult to implement, frequently error-prone, and lead to inconsistent behavior across runtimes. Bun's "Direct Streams" optimization takes a deliberately and observably non-standard approach, bypassing much of the spec's machinery entirely. Cloudflare Workers' IdentityTransformStream provides a fast-path for pass-through transforms but is Workers-specific and implements behaviors that are not standard for a TransformStream. Each runtime has its own set of tricks and the natural tendency is toward non-standard solutions, because that's often the only way to make things fast.
