Dithering algorithms

Floyd-Steinberg — error-diffusion for smooth gradients
Ordered (Bayer 4×4) — classic retro pattern look
Ordered (Bayer 8×8) — larger pattern, more visible texture
Adjustable color count from 2 to 32 colors

FAQ

What is dithering?

Dithering is a technique that creates the illusion of more colors by arranging limited colors in patterns. It's widely used in retro games and pixel art.

Which algorithm should I choose?

Floyd-Steinberg produces smoother results that look like the original. Ordered dithering creates a more obvious pattern that looks intentionally retro.

How many colors should I use?

2–4 colors gives a very retro Game Boy look. 8–16 colors is typical for NES/SNES-era pixel art. 24–32 preserves more detail.
