What is Dithering in Digital Media?
Dithering is a classic digital graphics technique used to approximate color gradients and continuous shaded textures when using restricted color palettes (such as 1-bit monochrome, Game Boy 4-color olive screens, CGA, or Commodore 64 colors).
By positioning small patterns of contrasting pixels or halftone dots next to each other, the human eye perceives intermediate shades that do not exist in the physical palette, producing retro pixel art graphics popularized in Macintosh computers, early arcade games, and modern cyberpunk art styles.
Supported Dithering Algorithms & Effects
Floyd-Steinberg
Classic 75% error diffusion algorithm distributing quantization error to neighboring right, down-left, down, and down-right pixels for smooth organic stippling.
Halftone Dot Screen
Simulates CMYK newspaper print matrices with circular halftone dot clusters that adjust diameter based on localized pixel brightness.
ASCII Text Matrix
Translates pixel luminance into ASCII characters (`.:-=+*#%@` or `░▒▓█`) for vintage terminal computer aesthetics.
