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.

Advocacy groups like the Center for Democracy and Technology (CDT) quickly came out against the president’s threats. “This action sets a dangerous precedent. It chills private companies’ ability to engage frankly with the government about appropriate uses of their technology, which is especially important in national security settings that so often have reduced public visibility,” said CDT President and CEO Alexandra Givens, in a statement shared with Engadget. “These threats undermine the integrity of the innovation ecosystem, distort market incentives and normalize an expansive view of executive power that should worry Americans all across the political spectrum.”
