Four dithering algorithms

Floyd-Steinberg — Classic error diffusion. Smooth gradients, minimal patterning. Best for photos with fine tonal range.
Bayer 4×4 — Ordered dithering. Most similar to what C64 software actually used — crisp, geometric grid pattern.
Atkinson — Apple Mac era diffusion. Softer than Floyd-Steinberg, spreads error over more neighbours, great for portraits.
No Dither — Raw palette mapping. Produces blocky, flat-colour look — the most extreme 8-bit aesthetic.

Dithering creates the illusion of more colours by mixing pixels in patterns that trick the eye into seeing a blend. The Commodore 64 relied on it heavily to overcome the VIC-II chip's strict 16-colour limit — mixing light blue and white to suggest sky blue, for instance.
