Dither Tool

Apply dithering patterns to images to simulate colors unavailable in limited palettes or to achieve distinctive retro visual effects. Dithering uses strategic dot patterns to create the optical illusion of colors and gradients that aren't directly representable—similar to how newspaper halftones use tiny dots to simulate continuous tones.

Multiple dithering algorithms produce different visual characteristics: Floyd-Steinberg error diffusion creates natural-looking gradients by spreading quantization errors to neighboring pixels; ordered (Bayer) dithering produces regular geometric patterns with a distinctive digital aesthetic; Atkinson dithering (famous from classic Macintosh) creates a specific nostalgic look. Each algorithm has unique visual character suited to different artistic goals.

Retro graphic designers recreating vintage computer aesthetics apply period-appropriate dithering algorithms. Artists creating pixel art and low-color illustrations use dithering for shading effects. Color reduction workflows apply dithering to smooth harsh banding when converting to limited palettes. E-ink and 1-bit display developers prepare images for binary output devices. Designers creating intentionally lo-fi aesthetics achieve specific stylized looks. Anyone working with limited color palettes—whether by artistic choice or technical constraint—will find dithering essential for achieving smooth visual results.
