# Adwaita × Ubuntu Yaru — composed image prompt

# Adwaita carries the structure and Ubuntu Yaru 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 Adwaita (style, 2011–) and their accent from Ubuntu Yaru (style, 2018–).

## What to make

Make the kind of thing Adwaita exists for: building a Linux desktop app that has to hold the same structure in both the light and the dark setting, or adding a custom widget by riding on the existing style classes and colour variables instead of hard coding values. Choose one subject and hold it across all four.

## Structure comes from Adwaita

- A single header bar across the top of the window, laid out on three alignment points with the window heading in the centre
- Header bar buttons carry no background and no border, leaving only the symbol and the label on the surface
- Monochrome symbolic icons drawn at 16 by 16 pixels with 2 pixel strokes and no perspective
- A published palette of five steps per hue, including Blue 3 at #3584e4

Composition: Put a header bar at the top, main actions at the start, the heading in the middle, menus at the end. Always leave blank area so the bar can be dragged. Group buttons with spacing rather than by linking them. Type and lettering: Identify a control with either an icon or a label, not both. The exceptions are sidebar rows and view switchers.

## Accent comes from Ubuntu Yaru, used sparingly

- Light window body contrasted with a dark header bar
- Ubuntu orange for selection and focus
- Suru-derived icons based on circles, squares and vertical or horizontal oblongs
- One-pixel icon edge, restrained gradient and lower shadow

Let one material quality come from it: Reuse the Suru palette, restrained gradients and translucent dark outlines to keep icons from drifting apart.

## Colour and feeling

Build the ground on #f6f5f4, carry the structure in #3584e4 and #241f31, and let a single accent come from #E95420. These are read off real works, so a direction rather than a fixed palette.
Feeling to carry: technique, calm, trust, intimacy.

## Where they fight

- Adwaita and Ubuntu Yaru both belong to Platform Screen Languages, so the difference is small. Push the roles further apart than feels comfortable.

## What goes wrong

- Adwaita: Hard coded colour values only break once someone switches to the dark or high contrast style, which is exactly the state the author never looks at.
- Ubuntu Yaru: Large overrides of Adwaita collide with application styling. Contain Ubuntu identity in color, headers and iconography instead of restructuring widgets.

## 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.
