# Dithering (ディザリング) — image generation prompt
# IndexStyle No.585 — https://indexstyle.org/styles/dithering
# Style descriptors only. This prompt names no artist, studio, brand or work.

Produce four original images in the visual language of Dithering, a technique from Digital Image Techniques, 1960s–.

## What to make

Make the kind of thing this style exists for: preserving photographic tone on low-color displays and e-paper, or using the grain of early computer images as deliberate digital material. Choose one subject and hold it across all four images.

## What has to be visible

- Two or more pixel colors mixed as checks or grain
- High-frequency dots spreading around tonal boundaries
- Apparent gradients made from a fixed palette
- A pattern up close that becomes an intermediate color at normal distance

Someone who knows this style should be able to point at each of these in the finished image.

## How to build it

- Layout and structure: Build broad tonal fields but control diffusion around contours and copy
- Type and lettering: Use bitmap or simple sans type that remains intact at low resolution
- Material and surface: Fix the palette first, then pass quantization error to neighboring pixels or place dots with a threshold matrix
- Colour: #F2F0E8 carries the ground, #6E65A8 is the colour the style is remembered by, #141414 holds text and outlines. Read off real works, so treat them as a direction rather than a fixed palette.
- What it should feel like: technique, nostalgia, play

## What goes wrong

Adding monochrome noise is not dithering. The limited colors must approximate the source value.

## Across the four

Keep every cue above present in all four. Vary the framing, the scale and the arrangement so the set shows the range this style covers rather than four versions of one picture.

## Constraints

- Do not imitate, reference or name any specific artist, studio, brand, character or copyrighted work.
- Do not reproduce the composition of an existing work.
- Produce original compositions in the general period language described above.
