Dithering in colour is a technique used to create the illusion of color depth in images that contain limited color palettes. The discussion reflects on the negative impacts that certain color palettes, particularly linearized RGB palettes, have on color representation. Comments highlight how these palettes can obscure details and render colors such as purples and yellows inaccurately. Users express concerns about perceptual accuracy and discuss preferences for different palettes when viewed on devices like smartphones. Overall, dithering remains an essential method for enhancing visual output in constrained environments, but its effectiveness is significantly influenced by the choice of color palette used.
