# Dithering × Halftone — composed image prompt
# IndexStyle — https://indexstyle.org/compose?ids=dithering+halftone
# Dithering carries the structure and Halftone appears as the accent.
# Style descriptors only. This prompt names no artist, studio, brand or work.

Produce four original images that take their structure from Dithering (technique, 1960s–) and their accent from Halftone (technique, 1880s–).

## What to make

Make the kind of thing Dithering 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.

## Structure comes from Dithering

- 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

Composition: 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.

## Accent comes from Halftone, used sparingly

- Large and small dots on one fixed pitch
- Light and shade made by dot area
- Rosettes from differently angled color screens
- An image that changes between normal and magnified viewing

Let one material quality come from it: Set line frequency, dot shape, screen angle and ink color, then translate tone into dot area.

## Colour and feeling

Build the ground on #F2F0E8, carry the structure in #6E65A8 and #141414, and let a single accent come from #D94036. These are read off real works, so a direction rather than a fixed palette.
Feeling to carry: technique, nostalgia, play, rebellion.

## Where they fight

- Dithering and Halftone are techniques rather than looks. Decide which one runs last in the process, because that is the one that will show.
- Dithering and Halftone stand roughly 80 years apart. Keep one of them recognisably period rather than letting both drift into the middle.

## What goes wrong

- Dithering: Adding monochrome noise is not dithering. The limited colors must approximate the source value.
- Halftone: Polka dots are not halftone. Dot size must carry continuous tone in relation to printing resolution.

## Across the four

Keep the roles fixed in all four. Vary the framing, the scale and the arrangement so the set shows what this pairing can do 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 languages described above.
