# Style descriptors only. This prompt names no artist, studio, brand or work.

Produce four original images in the visual language of Palm OS Interface, a style from Platform Screen Languages, 1996–2009.

## What to make

Make the kind of thing this style exists for: handling calendar, contacts and notes quickly with an extremely small display and few inputs, or reconstructing an early PDA from its stylus-centered sequence, not only its pixel surface. Choose one subject and hold it across all four images.

## What has to be visible

- A roughly 160 by 160 low-resolution monochrome screen
- Title at upper left and Category pop-up at upper right
- A Command Bar rising from the lower edge and four application buttons
- Thin one-bit icons, rules and the Graffiti input area

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: Fix Title and Category above, the list in the middle, and commands and input below to reduce screen changes
- Type and lettering: Use a sturdy bitmap face that separates letters at small sizes and reduce labels to one word
- Material and surface: Work in one-bit black and white, using thin rules, reversed selection and roughly 16-pixel icons for state
- Colour: #E8E6D8 carries the ground, #7D8277 is the colour the style is remembered by, #161916 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, trust, nostalgia

## What goes wrong

Monochrome pixel UI alone is not Palm OS. Preserve the division of work among stylus, hardware keys, Graffiti and on-screen commands.

## 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.
