# HarmonyOS Design × Material You — composed image prompt
# IndexStyle — https://indexstyle.org/compose?ids=harmonyos+material-you
# HarmonyOS Design carries the structure and Material You 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 HarmonyOS Design (style, 2019–) and their accent from Material You (style, 2021–).

## What to make

Make the kind of thing HarmonyOS Design exists for: recomposing the same information across phones, tablets, vehicles and wearables, or explaining continuity across devices through shared cards, motion and hierarchy. Choose one subject and hold it across all four.

## Structure comes from HarmonyOS Design

- Large rounded cards grouping information by function
- Wide space on light fields with a few saturated accents
- Arcs, concentric circles and gentle scaling for operation states
- Cards and variable type recomposed to suit device size

Composition: Group by function; spread cards sideways on wide screens and stack them by importance on small ones. Type and lettering: Adapt the weight and width of a variable sans to the display and enlarge short headings and numbers.

## Accent comes from Material You, used sparingly

- Harmonized colors derived from wallpaper
- Large rounded cards and controls
- Selection changes both color and shape
- Broad spacing and large display type

Let one material quality come from it: Generate tonal palettes from a seed, then assign them to semantic surface and content roles.

## Colour and feeling

Build the ground on #F5F7FA, carry the structure in #0A59F7 and #172033, and let a single accent come from #6750A4. These are read off real works, so a direction rather than a fixed palette.
Feeling to carry: futurity, intimacy, technique, play.

## What goes wrong

- HarmonyOS Design: Rounded cards alone are not HarmonyOS. Information priority and action continuity must survive the move between devices.
- Material You: Automatic color generation alone can produce unreadable interfaces. Contrast and semantic roles come first.

## 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.
